Find the indicated measure in parallelogram abcd m

Check the picture below.

those angles in red are alternate interior with the angles at A and D, therefore, equal.

the answer is a

step-by-step explanation:

(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
