3. (x+2)(x−5)

Step-by-step explanation:

Question One.

Factor 8x+12

8x+12

4(2x+3)

Question Two.

Factor [tex]x^{2}[/tex]−3x−10

The middle number is -3 and the last number is -10.

Factoring means we want something like:

(x+_)(x+_)

We need to figure out which numbers go in the blanks.

You will need two numbers. They need to...

Add together to get -3.

Multiply together to get -10.

2+-5=-3

2·-5=-10

Fill in the blanks.

(x+2)(x-5)

Answer:

(x+2)(x−5)

Answer:

x would equal 40

Step-by-step explanation:

x+(2x-5)+(x+25)=180

4x+20=180

x=40

Answer:

y = 2x +14

Step-by-step explanation:

We need to convert the given equation into slope intercept form ,

=> y - 6 = 2(x+4)

=> y -6= 2x + 8

=> y = 2x +8+6

=> y = 2x + 14

Question: Find the circumference of the circle to the nearest hundredth

d = 11cm

Answer:

34.54 cm

Step-by-step explanation:

Applying,

P = πd...................... Equation 1

Where P = Circumference of perimeter of the circle, d = diameter of the circle, π = pie

From the question

Given: d = 11 cm

Constant: π = 3.14

Substitute these values into equation 1

P = (3.14×11)

P = 34.54 cm

Answer:

y = 41°

Step-by-step explanation:

∡ y and 139° are adjacent angles and sum to 180° , that is

∠ 1 + 139° = 180° ( subtract 139° from both sides )

∠ 1 = 41°

Answer:

Lets say there's a quadratic equation → ax² + bx = -c

Lets make one side zero which gives → ax² + bx + c = 0

From the above equation ,

For example :- x² - 12x = -35.

Lets make one side zero → x² - 12x + 35 = 0 . Now, lets break -12x into two real numbers 'p' & 'q' such that p + q = -12x & pq = 35. Prime factors of 35 are 1 , 5 & 7. If we take 5 & 7 as 'p' & 'q' then p + q = 5 + 7 = 12. but as we need -12 , the values of 'p' & 'q' are -5 & -7.

⇒ [tex]x^2 -5x - 7x + 35 = 0[/tex]

⇒ [tex]x(x - 5) - 7(x - 5) = 0[/tex]

⇒ [tex](x - 5)(x - 7) = 0[/tex]

⇒ [tex]x = 5 \: or \: 7[/tex]

Lets take another example :- x² + 4x = 1.

Lets make one side zero → x² + 4x - 1 = 0 . Now , lets split +4x into into two real numbers 'p' & 'q' such that p + q = +4x & pq = -1 . Prime factors of 4 are 1 & 2 only. But there's no such combination of its primes such that their sum would be equal to 4. So, the quadratic equation can't be solved by factorisation method. Now, lets bring -1 to Right Hand Side & try solving by completing squares method.

⇒ [tex]x^2 + 2 \times x \times 2 + 2^2 = 1 + 2^2[/tex]

⇒ [tex](x + 2)^2 = 1 + 4 = 5[/tex]

⇒ [tex]x + 2 = +\sqrt{5} \: \: or \: -\sqrt{5}[/tex]

⇒ [tex]x = (\sqrt{5} - 2) \: or \: (-\sqrt{5} -2)[/tex]

Conclusion:

First try making one side zero and try to solve the equation by factorisation method. If it got factorised , then you are done and if it didn't get factorised , then solve it by completing squares method.

Answer:

I'm assuming we're asking about the difference between:

[tex]ax^2 + bx + c = 0[/tex]

and

[tex]ax^2 + bx = -c[/tex]

Let's preface this by stating the obvious: there's no actual difference. Both equations are equivalent.

Now, it has a lot to do with our goal. Sometimes our goal is to write an equation concisely (then the "no-zero" way uses less characters), and sometimes we're dealing with a quadratic function of

[tex]y = ax^2 + bx + c[/tex]

in the second case, we wouldn't write

[tex]y - c = ax^2 + bx[/tex]

because it'd be confusing. That means that when we're looking for y=0 points of a quadratic equation, the way to convey that goal is that we're looking for the point where [tex]ax^2 + bx + c = 0[/tex] - so we preserve the structure of the quadratic function.

Answer:

Option B

Step-by-step explanation:

Average rate of change of a function between x = a and x = b will be,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

We have to calculate average rate of change of the given quadratic function between x = 0 and x = 2.

From the given graph,

f(2) = 6

f(0) = 10

Therefore, average rate of change = [tex]\frac{f(2)-f(0)}{2-0}[/tex]

                                                          = [tex]\frac{10-6}{2-0}[/tex]

                                                          = 2

Option B will be the answer.

3.14×12×12=452.16

Answer is 452.16

Answer:

The circle's area above is 452.39 I believe.

Step-by-step explanation:

Use A = pie*r^2 and d = 2 * r to solve this problem.

A = 1/4*pie*d^2 = 1/4*pie*24^2 = 452.38

Round and you have the area of the circle: 452.39

Answer:

A.

Step-by-step explanation:

64/4=16  80/5=16 They are multiplied by the same number so it is A

Answer:

3220 cm²

Step-by-step explanation:

Lets find the area of the two triangles

I am making a modification:

Both of the triangles are the same, so I wont divide by 2 using the area of triangle formula 1/2(b * h) because we end up multiply by 2

Area of triangles = 15 cm x 28 cm = 420 cm²

Area of front facing parallelogram = 24 cm x 4(10)cm = 100(10)cm = 1000 cm²

Area of back facing parallelogram = 17 cm x 40 cm = 680 cm²

Area of bottom parallelogram = 40 cm x 28 cm = 1120 cm²

Total Surface area = 420 cm² + 1000 cm² + 680 cm² + 1120 cm² = 1100 cm² + 2120 cm² = 3220 cm²

Answer:

The area of the shaded region is 11.606 square centimeters.

Step-by-step explanation:

The area of the shaded region is obtained by subtracting the area of the triangle from the area of the circular section. The area of the triangle ([tex]A_{t}[/tex]), in square centimeters, can be calculated by the Heron's formula:

[tex]A_{t} = \sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}[/tex] (1)

[tex]s = \frac{a + b + c}{2}[/tex] (2)

Where:

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Lengths of the sides of the triangle, in centimeters.

[tex]s[/tex] - Semiperimeter, in centimeters.

If we know that [tex]a = 10.50\,cm[/tex] and [tex]b = c = 9.28\,cm[/tex], then the area of the triangle is:

[tex]s = \frac{10.50\,cm + 2\cdot (9.28\,cm)}{2}[/tex]

[tex]s = 14.53\,cm[/tex]

[tex]A_{t} = \sqrt{(14.53\,cm)\cdot (14.53\,cm - 10.50\,cm)\cdot (14.53\,cm - 9.28\,cm)^{2}}[/tex]

[tex]A_{t} \approx 40.174\,cm^{2}[/tex]

And the area of the circular section ([tex]A_{c}[/tex]), in square centimeters, is determined by the following formula:

[tex]A_{c} = \left(\frac{\theta\cdot \pi}{360} \right)\cdot r^{2}[/tex] (3)

Where:

[tex]r[/tex] - Radius of the circle, in centimeters.

[tex]\theta[/tex] - Internal angle, in sexagesimal degrees.

If we know that [tex]r = 9.28\,cm[/tex] and [tex]\theta = 68.9^{\circ}[/tex], then the area of the circular section is:

[tex]A_{c} = \left(\frac{68.9}{360}\right)\cdot \pi\cdot (9.28\,cm)^{2}[/tex]

[tex]A_{c} \approx 51.780\,cm^{2}[/tex]

Finally, the area of the shaded region ([tex]A[/tex]), in square centimeters, is:

[tex]A = A_{c} - A_{t}[/tex] (4)

[tex]A = 51.780\,cm^{2}- 40.174\,cm^{2}[/tex]

[tex]A = 11.606\,cm^{2}[/tex]

The area of the shaded region is 11.606 square centimeters.

Answer:

Mean: 12.6

Median: 12

Mode: None

Step-by-step explanation:

To find the mode, add everything up.

12 + 9 + 17 +15 + 10 = 63. Then, divide by five.

63 ÷ 5 = 12.6

To find the median, put the numbers from least to greatest. Then, highlight the one in the middle.

9, 10, 12, 15, 17

To find the mode, look for the number that appears the most. Because each number appears once. So, put "none" in the box.

Have a wonderful day!

Answer:

4.5

Step-by-step explanation:

Step-by-step explanation:

|3x - 4| = 6

3x-4 = 6 or 3x-4 = -6

3x=6+4 3x=-6+4

3x=10 3x = -2

x= 10/3 x = -2/3

so, x1= 10/3 or x2 = -2/3

Given,

[tex]x = 7[/tex]

Substitute the value of 'x' in the equation 3x (x - 2).

One way :-

[tex]3x(x - 2) \\ = 3 \times 7(7 - 2) \\ = 21(5) \\ = 21 \times 5 \\ = 105[/tex]

Second way :-

[tex]3x(x - 2) \\ = 3x {}^{2} - 6x \\ = 3 \times (7) {}^{2} - 6(7) \\ = (3 \times 49) - (6 \times 7) \\ = 147 - 42 \\ = 105[/tex]

Answer:

y = 8 - 5x, y(-2) = 18, y(0) = 8, y(3) = -7

Step-by-step explanation:

y + 5x = 8

y = 8 - 5x

y(-2) = 8 - 5*(-2) = 8 + 10 = 18

y(0) = 8 - 5*(0) = 8 - 0 = 8

y(3) = 8 - 5*(3) = 8 - 15 = -7
