D) 22*5*7

Step-by-step explanation:

This one is best done by doing a pre factor.

140 = 14 * 10 Now all you need do is factor those two numbers.

140 = 7*2 * 5 * 2

Rearranging this you get 2 * 2 * 5 *7

Solve for x: 4(x + 2) = 3(x - 2)

Pani-rosa [81]

Answer:

x = -14

Step-by-step explanation:

Step 1: Write equation

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

Step 2: Solve for x

Distribute: 4x + 8 = 3x - 6
Subtract 3x on both sides: x + 8 = -6
Subtract 8 on both sides: x = -14

Step 3: Check

Plug in x to verify it's a solution.

4(-14 + 2) = 3(-14 - 2)

4(-12) = 3(-16)
