To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.

$\frac{3}{4}x-1=\frac{1}{2}x+7$ [subtract both sides by 1/2x]

$\frac{1}{4}x-1=7$ [add both sides by 1]

$\frac{1}{4}x=8$ [multiply both sides by 4]

$x=32$

Now that we know x, we can plug it into each expression to find teh length of each side.

$\frac{3}{4}(32)-1$ [multiply]

$24-1$ [subtract]

$23$

Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.

23+23+23+23=92 or 23×4=92

Since we know that the perimeter is 92 units, the answer is D.

Its subtract 12.

Step-by-step explanation:

The first question mark is positive 6.

6-12= -6

The second question mark is -22.

Negative 10 minus 12 equals negative 22

Once you understand integers, it will be really easy. I was in 6th grade last year.
