It is quite simple actually since it is simple division with the negative rules.
Just simplify the problem and use the negatives to determine if it is positive or negative. (two negatives equal a positive and one negative equals a negative)
<span>THE ANSWER:
</span>112 - 7 = 105
105 <span>÷ 7 = 15
</span>x = 15
Part A you would use 200-L ( since you have 400 feet total 200 feet would equal length plus width)
Part B 200 - 80 = 120
Part C 200-90 = 110
area = 90 x 110 = 9900 square feet
It’s A, cuz the 4*2 equals 8
