Answer: D. 84 ft^2
Step-by-step explanation: The area of a trapezoid is (a+b)/2 x h. A and B are the bases, and h is the height. Plug in the numbers.
(8+16)/2 x 7 = 84
Your answer would be 84 ft^2. D.
14 * 12 = 168
(12*8) / 2 = 48
216 cm ^2
Step-by-step explanation:
ok so just take 4×10=40
-6^40=20
4/x = 7/9
Cross multiply:
4 * 9 = x * 7
36 = 7x
Divide both sides by 7:
x = 36/7
x = 5.1
Answer: 9x+3
Step-by-step explanation: 4x-(-3 - 5x)
=4x+ 3 +5x [open the bracket]
=9x+3
