you were wrong, the correct answer is the top one: f(x) = -x^2 + 8x - 15
Answer:
A =166.025 ft^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) h
where (b1+b2) is the sum of the bases and h is the height
A = 1/2 (22.9)*14.5
A =166.025 ft^2
Answer:
MON = 130°
Step-by-step explanation:
LOM + MON = 180°
In other words
4z + 30° + 8z + 90 = 180°
12z + 120 = 180
60 = 12z
z = 5
5 x 8 = 40 + 90 = 130°
