Answer:
135 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h(a + b)
where h is the height and a, b the parallel bases
Here h = 9, a = 13 and b = 17 , thus
A = × 9 × (13 + 17)
= 0.5 × 9 × 30
= 135 cm²
24 h in 1 day
just divide the hours by 24
168 : 24 = 7
The first option is correct. For the following question, the simplified expression for the volume is 8x3 + 14x2 + 3x.
