2x+4(2x+7)=3(2x+4)<br> What is x
Rainbow [258]

Answer:

x = -4

Step-by-step explanation:

2x+4(2x+7)=3(2x+4)

Distribute

2x+8x + 28 = 6x +12

Combine like terms

10x +28 = 6x +12

Subtract 6x from each side

10-6x+28 = 6x +12 -6x

4x +28 = 12

Subtract 28 from each side

4x+28-28 = 12-28

4x = -16

Divide each side by 4

4x/4 = -16/4

x = -4

Q # 4 Simplify the product
timama [110]
For this case we have the following product:
 (x-4) (x + 3)&#10;
 We must use the distributive property correctly to solve the problem.
 We have then:
 x ^ 2 + 3x - 4x - 12&#10;
 Then, we must add similar terms.
 We have then:
 x ^ 2 - x - 12&#10;
 Answer:
 
The final product is given by:
 
x ^ 2 - x - 12&#10;
