Answer:
a = -4.3
Step-by-step explanation:
a+(−1.2)=−5.5
a - 1.2 = - 5.5
a = - 5.5 + 1.2
a = - 4.3
2xy, -xy, and 1/2xy because they contain the same variables
Let the length be 9x and the width = 8x
Perimeter = 2(l + w) = 2(9x + 8x) = 2(17x) = 34x = 68
x = 68/34 = 2
9x = 9(2) = 18 ft
8x = 8(2) = 16 ft
Therefore, dimensions are 18 ft by 16ft
