Answer:
.5 < x < 16.5
Step-by-step explanation:
The smallest x can be is greater than the difference of the other two sides
8.5 -8 = .5
The largest x can be the less than the sum of the two sides
8.5+8 = 16.5
.5 < x < 16.5
Answer:
(7,5)
Step-by-step explanation:
2(12 - y) + 3y = 29
24 - 2y + 3y = 29
24 + y = 29
y = 5
x = 12 - 5
x = 7
Step-by-step explanation:
normally there are 6 surface areas on a prism (or simply "box").
for the lateral surface area we ignore the indicated (shaded) areas as to and bottom. that leaves us with the 4 white ones.
so, we have 2 rectangles of 4×3 and 2 rectangles (the missing side lengths must be identical to the other specified lengths given the graphic, otherwise the sides would not fit together to build the prism) of 1.5×4.
the total lateral surface area is therefore
2×3×4 + 2×1.5×4 = 24 + 12 = 36 ft²
