Answer:
7 inches
Step-by-step explanation:
formula for a trepezoid is 1/2(a+b)*h
1/2(5+x)X3=18 (now make x the subject)
(5+x)X3=36
5+x=12
x=7
so the other base is 7in
(x - 3)(x + 3)²
(x - 3)(x + 3)(x + 3)
(x(x + 3) - 3(x + 3))(x + 3)
(x(x) + x(3) - 3(x) - 3(3))(x + 3)
(x² + 3x - 3x - 9)(x + 3)
(x² - 9)(x + 3)
x²(x + 3) - 9(x + 3)
x²(x) + x²(3) - 9(x) - 9(3)
x³ + 3x² - 9x - 27
The answer is 2.
Assuming the movie screen is rectangular, the answer would be 8 meters tall. Because the perimeter is 2 times width plus 2 times height, you can subtract 36 (18 times 2) from 54. This leaves you with 18, which is 2 times height. Divide both by two and you get 9
