Answer:
n = -28
Step-by-step explanation:
-4 = 10 + n/2
first step, subtract 10 from each side to get:
-14 = n/2
cross-multiply to get:
n = -28
-53/200 is what your fraction will be simplified to
Let x be the width
Lenght = 10x + 8.1
(10x + 8.1)2 + 2x = 515.6
22x = 499.4
x = 22.7
Area = l*w
= 22.7*235.1
= 5336.77
= 5340( nearest tens)
