Answer:
A)18in.
Step-by-step explanation:
Given,
A trapezoid Area= 216 sq
The length of its longer base=2x
The length of its shorter base= x
Height of Trapezoid = 8in
Area of Trapezoid= 1/2h(a+b)
216=1/2 x 8(2x+x)
216=4(2x+x)
216/4=3x
54=3x
54/3=x
18=x
Length of shorter base=18
Length of longer base=2x18=36
Hence, the length of the shorter base is 18in
Option A) is correct
First if this expression is true the result is -8x-3y+3∧2x
Second if you mean (3∧2)x=9x than the result is x-3y
Good luck!!!
