How do I solve 6(5 - 2x) + 12 = -66?
ladessa [460]

Answer:

x = 9

Step-by-step explanation:

Step 1: Write equation

6(5 - 2x) + 12 = -66

Step 2: Solve for <em>x</em>

  1. Distribute 6: 30 - 12x + 12 = -66
  2. Combine like terms: 42 - 12x = -66
  3. Subtract 42 on both sides: -12x = -108
  4. Divide both sides by -12: x = 9

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

6(5 - 2(9)) + 12 = -66

6(5 - 18) + 12 = -66

6(-13) + 12 = -66

-78 + 12 = -66

-66 = -66

Find the area of the rectangle.
aev [14]

Answer:

69y+23

Step-by-step explanation:

The area of a rectangle will always be length times width or width times length, doesn't matter which way.

In this case, the width is 3y+1 miles and the length is 23 miles. So, the area is 23(3y+1)=23*3*y+23*1=69*y+23.

So, the area is \boxed{69y+23} and we're done.
