Here is my question Which statement can be used to classify this triangle as an isosceles triangle?
Angle F is a right angle.

Sides DE and EF are congruent.

Sides FD and DE are congruent.

Sides EF and FD are congruent.

Sides EF and FD are congruent

Step-by-step explanation:

an isosceles triangle has two sides that are congruent and the two sides need to meet at then angle that is different from the other two base angles

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
