<h2><em><u>
Answer:</u></em></h2>
Total Surface Area = 375
<h2><em><u>
Step-by-step explanation:</u></em></h2>
You need to find the area of the ceiling, floor, the two rectangle walls and the two trapezoid walls
<u>Area of the ceiling:</u>
c = length * width
c = 9*6.5 = 58.5
<u>Area of the 2 rectangle walls:</u>
w = 2(length * width)
w = 2(9 * 8)
w = 2(72)
w = 144
<u>Area of floor:</u>
f = 9 * 7.5
f = 67.5
<u>Area of the two trapezoids:</u>
a = 6.5
b = 7.5
h = 7.5
Total Surface Area = c + w + f + t
Total Surface Area = 58.5 + 144 + 67.5 + 105
Total Surface Area = 375
Answer:
5x + 30
Step-by-step explanation:
5(5+x)
=(5)(6) + (5)(x)
=30 + 5x or 5x + 30
Answer:
108 %
Step-by-step explanation:
Answer:
x = -2 or x = -1/2
Step-by-step explanation:
We can just set up an equation where the quadratic is equal to -10, and then solve the equation:
Now, factor:
The first term should be 7
a1 = (224) / (2)6 - 1 = 7
