Answer:
the correct ls D) = 12c^2-15
Step-by-step explanation:
Product means to multiply
3c (4c-5)
= (3c)(4c+5)
= (3c)(4c)+(3c)(-5)
= 12c^2-15
Oh and I got it correct on the USAPERtest
Step-by-step explanation:
Xm = (-3+3)/2 = 0/2 = 0
Ym = (2-2)/2 = 0/2 =0
so, the midpoint (Xm, Ym) is (0 , 0)
The formula for the area of a trapezoid is:
A= (a+b)/2*h
A=150
h=10
b=14
a=?
So we need to solve for a. Let's plug in the values that we do know...
A= (a+b)/2*h
150=(a+14)/2*10
150=(a/2+14/2)*10
150=(a/2+7)*10
Divide both sides by 10
15=a/2+7
subtract 7 from both sides
8=a/2
multiply both sides by 2
16=a
The other base is 16
