Which expression is equal to 2x + 4(3x − 2) for all possible values of x?
Ipatiy [6.2K]
Answer: 2( 7x - 4 )

Explanation:

First let’s distribute the 4 to (3x - 2) by multiplying each term by 4.

2x + 4(3x - 2) =
2x + 4 • 3x - 4 • 2 =
2x + 12x - 8

Next we combine like terms:
2x + 12x - 8 =
14x - 8

None of the answers without parenthesis match the formula above so I will factor out a 2

14x - 8
= 2( 7x - 4 )

Notice how I factored out the 2 putting the result of dividing the equation by 2 inside the parenthesis and then moving a 2 to the outside of the parenthesis.

alexira [117]

Answer:

  • 784 in²

Step-by-step explanation:

Let the original side is x.

1 foot = 12 inches

<u>New sides of a rectangle are:</u>

  • x + 12 and x - 4

<u>The area of rectangle is:</u>

  • (x + 12)(x - 4) = 960

<u>Solve for x:</u>

  • x² + 8x - 48 = 960
  • x² + 2*4*x + 16 - 64 = 960
  • (x + 4)² = 1024
  • x + 4 = 32
  • x = 28

<u>Area of the original blanket:</u>

  • A = 28² = 784 in²
