Answer:
the width is 7 inches
Step-by-step explanation:
A = l * w
14 = 2 * w
what does w equal?
14 / 2 = 7
2 * w / 2 = w
7 = w
Find the area of trapezoid.
1/2(6+10)(3) = 24
Now multiply 24 by $4 to find the total cost.
24 * 4 = 96
So the total cost is $96
Hope this helps :)
-2(-2)^4 + 5(-2)^2 - 4
-2(-2)= 4. 4^4= 16
5(-2)= -10. -10^2= 100 - 4= 96
96 + 16= 112
Answer: 112
