The last one is incorrect
Answer:
C) 550 feet squared
Step-by-step explanation:
Imagine how the surface area of the given figure differs from the surface area of a prism 10 ft by 15 ft by 5 ft without the cutout in the top center. The three 5×5 ft squares that would need to be added to make the prism are of exactly the same area as the three 5×5 ft squares that are the sides and bottom of the cutout.
That is, the area is no different from the area of a 10 ft by 15 ft by 5 ft rectangular prism. That area is ...
A = 2(LW +WH +LH) = 2(10·15 +15·5 + 10·5) ft² = 550 ft²
Answer:
1. q = 3
2. w = 9
Step-by-step explanation:
1.
-2q - 5 = -11
Add 5 to both sides:
-2q - 5 + 5 = -11 + 5
-2q = -6
Divide both sides by 2:
-2q ÷ 2 = -6 ÷ 2
-q = -3
Divide both sides by -1:
-q ÷ -1 = -3 ÷ -1
q = 3
2.
w/3 + 2 = 5
Subtract 2 from both sides
w/3 = 3
Multiply both sides by 3:
w = 9

Answer:
x = 6
Step-by-step explanation:
As before, ray BG is an angle bisector. This makes CG and AG equal.
4x - 16 = 2x - 4
2x - 16 = -4
2x = 12
x = 6
To check:
4(6) - 16 = 2(6) - 4
24 - 16 = 12 - 4
8 = 8
