What expression is equivalent to -4x-36
A. 4(x-9)
B.2(2x-18)
C.-2(2x- 18)
D.-4(x+9)

Answer:

Make the variables different then just try random numbers

Step-by-step explanation:

Answer:

Step-by-step explanation:

4(x-3)^2 = 80

4x-12^2= 80              --- (distribute)

4x+144= 80          --- ( why a positive 144 because a (-) * a (-) = a (+)

4x =  (80-144)      --- ( subtract -144 from +144(do it on both sides)

4x = -64    --- (divide both sides by 4)

x= -16

Answer:

2√5 +3

Step-by-step explanation:

Isolate x:

4(x-3)^2 = 80

Divide both sides by 4.

(x-3)^2 = 20

Then take the square root of each side.

(x-3) = √20

Add 3 to each side.

x = √20 + 3

√20 can be rewritten as 2√5.

x = 2√5 + 3

The statement about rectangles and rhombuses that is always true is that both figures are quadrilaterals.

A quadrilateral is a closed, two-dimensional shape which has four straight sides.

In other word, a quadrilateral is a plane figure that has four sides or edges, and also has four corners or vertices.

Quadrilateral has four sides.

Rhombuses and rectangles have four sides. Therefore, they are both quadrilaterals.

Answer:

158 inches squared

Step-by-step explanation:

I am calling them Inches instead of centimeters because the image only shows inches as the unit.

To find the surface area, you need to add up all the rectangles' areas ([tex]lw[/tex]) shown to get the sum surface area.

Sides A & D: [tex]5 * 8 =40[/tex]

Sides B & F: [tex]3 * 8 =24[/tex]

Sides C & E: [tex]3 * 5 = 15[/tex]  (You get 5 inches from the edges, if you fold it into a rectangular prism, the side would have dimensions of 3x5.)

Then, you add all of the sides together.

[tex]A(40)+D(40)+B(24)+F(24)+C(15)+E(15)\\= 158[/tex]

Your total surface area would be 158 in.

Area of trapezoid = 4.5 Square meter

Step-by-step explanation:

Given:

Trapezoid bases = 3 meter and 1.5 meters

Height of trapezoid = 2 meter

Find:

Area of trapezoid

Computation:

Area of trapezoid = (1/2)(Sum of parallels side)(Height)

Area of trapezoid = (1/2)(3 + 1.5)(2)

Area of trapezoid = (1/2)(4.5)(2)

Area of trapezoid = 9 / 2

Area of trapezoid = 4.5 Square meter

The probability of getting a marble marked with a number greater than 4 is [tex]\frac{1}{9}[/tex].

Probability is the measure of happening or non-happening of outcomes of random experiment.

P(E) = Number of favorable outcomes/Total number of outcomes

where,

P(E) is the probability of an event.

According to the given question.

Total number of marbles in jar = 18

⇒ Total number of outcomes = 18  

( 6 red marbles, 6 black marbles, and 6 green marbles)

But it is given that, black or red marble is randomly selected.

Therefore, the total number of outcomes reduced to 12.

Numbers which are greater than 4 among 1 to 6 are 5 and 6.

Total number of numbers which are greater than 4 in jar = 2 × 3 =6

But we have to select only black or red marble.

Therefore,

Total number of favorable outcomes = 4

The probability of selecting a marble greater than 4 which are red

= [tex]\frac{4}{12} =\frac{1}{3}[/tex]

The probability of selecting a marble greater than 4 which are black

= [tex]\frac{4}{12} = \frac{1}{3}[/tex]

Therefore, the probability of getting a marble marked with a number greater than 4 [tex]=(\frac{1}{3}) (\frac{1}{3} )=\frac{1}{9}[/tex]

Hence, the probability of getting a marble marked with a number greater than 4 is [tex]\frac{1}{9}[/tex].

Answer:

1,960,000 square feet

Step-by-step explanation:

First let's round 679 to the nearest hundred. To do this we look at the 10s digit. If it is 5 or greater, we round up to 700 (because it is past halfway between 600 and 700), and is not we round down back to 600.

The 10s digit of 679 is 7, which is greater than 5. Therefore 679 rounded to the nearest hundred is 700.

Now let's look at 2828. The 10s digit here is 2, which is smaller than 5, therefore we round back down to 2800, which is closer than 2900.

Now we have 700 and 2800. To find the area, (assuming the yard is a rectangle) we multiply the length by the width together (these two values). 700x2800 = 1,960,000 square feet.

Answer:

34

Step-by-step explanation:

1. look at XV, and see that it equals 32 altogether.

WX is doubled the amount of WV. So it would be the same pattern on the other side.

2. 17*2=34

You might notice that 17-9=8, so wouldn't 34-16 be 8 as well. Nope, it would be doubled just like WX is doubled the amount of WV.

Answer:

Answer:

Then the solution set is all the values of x equal to or larger than -3.

Step-by-step explanation:

First, we know that each long strip represents an x.

Each white square represents 1.

Each grey square represents -1

Then, at the left side, we have:

8 long stripes.

12 white squares

Then we can write that as:

8*x + 12*1 ≥

And in the right side, we have 12 grey squares, then that is:

≥ 12*-1 = -12

Then the inequality is:

8*x + 12 ≥ -12

To find the solution set, we just need to isolate x.

First, we can subtract 12 in both sides to get:

8*x + 12 - 12 ≥ -12 - 12

8*x ≥ -24

Now we can divide both sides by 8

8*x/8 ≥ -24/8

x ≥ -3

Then the solution set is all the values of x equal to or larger than -3.

Answer:

Step-by-step explanation:

Given:

M(3, 2)

U(1, 3)

From midpoint to U:

(x, y) → (x - 2, y + 1)

To get from midpoint to V, we inverse the formula:

(x, y) → (x - 2, y + 1)

(x, y) → (x + 2, y - 1)

To find V:

(x, y) → (x + 2, y - 1)

(3, 2) → (3 + 2, 2 - 1)

(3, 2) → (5, 1)

Answer:

Step-by-step explanation:

y=x^2-8x+14

To write in vertex form, group the two x-terms to make a complete square, adjust the constant term accordingly

y = x^2-8x+16  -2

factor the first three terms on the right hand side

y = (x-4)^2 -2

This means that the vertex is at x-4 = 0, or x=4, and y=2.

Answer:

volume of square based prism = a²h

therefore

150 in³ = x²y

y = 1.5x ≈ 6.96 in

Answer:

84 cm²

Step-by-step explanation:

4 x 6 = 24

add up = 84

Answer:

y = 6 * 3ˣ

Step-by-step explanation:

y = a * bˣ

(-1 , 2):   2 = a * (b)⁻¹ = a/b               a = 2b

(2 , 54)  54 = a * b²  = 2b * b² = 2b³

b³ = 54/2 = 27          b = 3

a = 6

Function: y = 6 * 3ˣ
