Formula for the area of a trapezoid:
0.5 x h x (b + a)
b = 6 + 3 + 3 = 12
h = 8
a = 6
0.5 x 8 x (12 + 6)
4 x 18 = 72
A = 72 square units
Answer:
138 degrees
Step-by-step explanation:
A straight line/angle is 180 degrees so subtract 42 degrees from that to get 138 degrees.
I explained as best and simple as I could, I hope I helped!!!
-21/2 which in decimals would be -10.5. The actual numbers would be -14 and -7 and the median
A. 16x^4 + 16x - 16x - 64
C. (4x^2 + 8)(4x^2 - 8)
D. (16x^2 + 209x^2 - 2)
