Answer:

$area = 0.5 \times height \times width \\ = 0.5 \times (x + 2) \times (x +2 - 7) = 4 \\ 4 \div 0.5 = (x + 2)(x - 5) = 8 \\ {x}^{2} - 3x - 10 = 8 \\ {x}^{2} - 3x - 18 = 0 \\ (x - 6)(x + 3) = 0 \\ x = - 3 \\ x = 6$

Vlada [557]

-37 = n
 23

to solve for n, undo what is happening to the n. if the n is being divided by 23 to get -37, then multiply both sides by 23 to figure out what n is.

-37 * 23 = n * 23
 23

Rachel is making nachos for a party. The recipe calls for 2/3 cup of cheese for each plate of nachos. Part A: How many full plat

crimeas [40]

Part A:

We need to divide

5 ÷ 2/3

5/1 ÷ 2/3

5/1 * 3/2

15/2 or 7 1/2 plates of nachos.

Part B:

If Rachel can make 7 1/2 plates of nachos with 5 cups of cheese we need to multiply and subtract.

ma2/3 * 9 = 18/3 or 6 cups of cheese to make 9 plates

6 - 5 = 1 more cup of cheese she needs to make 9 plates

Best of Luck!
