Answer:
1 ) alternate interior angle
2) corresponding part of congruent triangle
3) vertically opposite angle
4)∆HED congruent to ∆FEG
5) parallel lines and alternate interior angle
f(x)=4x^3 - 6x^2 + 2x - 5
f(-2)
Replace X with -2:
4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =
Calulate the powers:
4(-8) - 6(4) +(-4) -5=
Multiply:
-32 - 24 -4 -5=
Subtract
-65
81 square inches
9*9*9=729
729/9(height of cube)=81(length and width of cube=area of cube)
