4(0.5n-3)=n-0.25(12-8n)
2n-12=n-3+2n
2n-12=3n-3
2n-3n=-3+12
-n=9
n = -9
Answer:the answer is C
Step-by-step explanation:
First, divide the the polygon into two quadrilateral.
Then find the area of both quadrilaterals
The area of the small rectangle = 4 x 3 = 12 square feet
The area of the bigger rectangle = (9 - 3) x 14 = 6 x 14 = 84 square feet
Add both areas:
12 + 84 = 96 square feet
Answer:
exact form: 13 over 6
