Pulling out like terms :

4.1 Pull out like factors :

-2y2 - 5y + 7 = -1 • (2y2 + 5y - 7)

Trying to factor by splitting the middle term

4.2 Factoring 2y2 + 5y - 7

The first term is, 2y2 its coefficient is 2 .

The middle term is, +5y its coefficient is 5 .

The last term, "the constant", is -7

Step-1 : Multiply the coefficient of the first term by the constant 2 • -7 = -14

Step-2 : Find two factors of -14 whose sum equals the coefficient of the middle term, which is 5 .

-14 + 1 = -13

-7 + 2 = -5

-2 + 7 = 5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 7

2y2 - 2y + 7y - 7

Step-4 : Add up the first 2 terms, pulling out like factors :

2y • (y-1)

Add up the last 2 terms, pulling out common factors :

7 • (y-1)

Step-5 : Add up the four terms of step 4 :

(2y+7) • (y-1)

Which is the desired factorization

Equation at the end of step

Theory - Roots of a product :

5.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

5.2 Solve : -y+1 = 0

Subtract 1 from both sides of the equation :

-y = -1

Multiply both sides of the equation by (-1) : y = 1

Solving a Single Variable Equation :

5.3 Solve : 2y+7 = 0

Subtract 7 from both sides of the equation :

2y = -7

Divide both sides of the equation by 2:

y = -7/2 = -3.500

Supplement : Solving Quadratic Equation Directly

Solving 2y2+5y-7 = 0 directly

Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula

Parabola, Finding the Vertex :

6.1 Find the Vertex of t = 2y2+5y-7

Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "t" because the coefficient of the first term, 2 , is positive (greater than zero).

Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.

Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.

For any parabola,Ay2+By+C,the y -coordinate of the vertex is given by -B/(2A) . In our case the y coordinate is -1.2500

Plugging into the parabola formula -1.2500 for y we can calculate the t -coordinate :

t = 2.0 * -1.25 * -1.25 + 5.0 * -1.25 - 7.0

or t = -10.125

Parabola, Graphing Vertex and X-Intercepts :

Root plot for : t = 2y2+5y-7

Axis of Symmetry (dashed) {y}={-1.25}

Vertex at {y,t} = {-1.25,-10.12}

y -Intercepts (Roots) :

Root 1 at {y,t} = {-3.50, 0.00}

Root 2 at {y,t} = { 1.00, 0.00}

Answer:

Angle C = 62.90°

Step-by-step explanation:

As given,

The perpendicular = 86

        Base = 44

As, we know that

tan(C) = [tex]\frac{Perpendicular}{Base} = \frac{86}{44} = 1.9545[/tex]

⇒C = [tex]tan^{-1}[/tex](1.9545) = 62.90°

Answer:

1. The corresponding sides of the two triangles must be proportional.

Step-by-step explanation:

Option 1, is the only statement that makes GHI = JKL true. If the triangles are congruent, it means that the sides have to be proportional.

The triangles GHI and JKL are similar, Δ GHI ≈ Δ JKL only if their two corresponding sides are proportional and one angle is also equal, so option 1 is correct.

Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.

Given:

The triangles GHI and JKL are similar, Δ GHI ≈ Δ JKL,

The condition for the similarity of the triangle are shown below,

Two triangles are said to be comparable if the ratio of one triangle's two sides to the two sides of another triangle is the same, and the angles that the two sides of both triangles inscribe are equal.

Thus, the sides have to be proportional.

To get our final answer, we need to follow PEMDAS, which is :

Parenthesis

Exponent

Multiply

Divide

Addition

Subtraction

These mean that this is the order you will solve by what is in the question, let us start with the parenthesis.

(2 + 3) fits this description, therefore we add them together :

4 * 5 - 12

There are no more parenthesis and also no more exponents, so move onto multiplying.

4 * 5 - 12

Answer:

D

Step-by-step explanation:

For each triangle, you are given two sides and the included angle (the one between those 2 sides). That's side-angle-side, so it is S-A-S.

The SAS Rule for Similar Triangles says that for 2 triangles X and Y, if you have the SAS of one and the SAS of the other, then X and Y are similar (same shape and proportions) if

(a) the angle in X is congruent (same) as the angle in Y

(b) the ratio between the two given sides in X is the same as the ratio between the two given sides in Y

For this particular problem, the ratio PR/PQ = 18/21 = 6/7 if you simplify by dividing both top and bottom by 3.

So we are looking for another triangle where we have the same ratio. (Put the smaller number on top, in the fraction.)

Answer A:  12/15 simplifies to 4/5, wrong answer

Answer B:  9/12 simplifies to 3/4, wrong answer

Answer C:  6/10 simplifies to 3/5, wrong answer

Answer D: 15/17.5 looks harder, because there is a decimal in it. But we know 17.5 is just 17 and a half, so I would first multiply top and bottom by 2

We get 30/35. That looks a lot better. Now it is easier to see we can divide both top and bottom by 5.

We get 6/7! That is the correct answer, so D is the triangle similar to PQR.

Answer:

1000 boys

Step-by-step explanation:

The ratio of the number of boys to girls is 4:5.

Every time you multiply 4 and 5 by the same whole number, you get a possible number of boys and girls in the same ratio.

There may be

4 boys and 5 girls, or

8 boys and 10 girls (multiplying 4 and 5 by 2), or

12 boys and 15 girls (multiplying 4 and 5 by 3), or

400 boys and 500 girls (multiplying 4 and 5 by 100),

but all these numbers are too low for there to be a difference of 250 between the numbers of boys and girls. Since we don't know the numbers of boys and girls, but know the ratio is 4:5, then we know that the ratio is also 4x:5x, by multiplying both numbers of boys and girls in the ratio by x.

There are 250 more girls than boys, so

5x - 4x = 250

x = 250

The number of boys is 4x.

4(250) = 1000

Answer: 1000 boys

Answer:303.48

Step-by-step explanation:

Length of a wire = 23 cm

Given that :

▪︎The wire was cut into two pieces.

▪︎The longer piece of wire is 7 cm longer than the shorter piece of wire.

Let the shorter piece of wire be x.

Then, the longer piece of wire = x+7

An equation that can be derived from these statements :

▪︎x + x + 7 = 23

Let us solve this equation :

[tex] = \tt x + x +7 = 23[/tex]

[tex] = \tt 2x + 7 = 23[/tex]

[tex] = \tt 2x = 16[/tex]

[tex] = \tt x = \frac{16}{2} [/tex]

[tex] \color{plum} \hookrightarrow \color{plum}x = 8[/tex]

Thus, the value of x = 8.

Which means :

Length of the shorter piece of wire = 8 cm

Length of the longer piece of wire = 8 + 7 = 15 cm

Since the length of the two wires add up to form 23 cm(8+15=23), we can conclude that we have found out the correct measures of each wire.

Therefore, the length of the shorter piece of wire = 8 cm

7b + 8b² + 3 + y + 2b + 2y + 2 =

[tex] \tt \dashrightarrow 7b + 8b^2 + 3 + y + 2b + 2y + 2 [/tex]

[tex] \tt \dashrightarrow 8b^2 + 7b + 2b + y + 2y + 2 + 3[/tex]

[tex] \tt \dashrightarrow 8b^2 + 9b + 3y + 5[/tex]

Hence, answer is 8b² + 9b + 3y + 5.

So, correct option is 4th one.

Step-by-step explanation:

multiplying by 0.25 is same as find the 1/4 of a number. it can also be said the number is reduced by 75% of itself or number is reduced by 3/4th of itself.

For example let the number be 100.

0.25*100=25 also 100/4=25 or 100-0.75*100= 25 or, 100-(3/4*100)= 25
