Plz as fast question: which shows a right triangle

D

Step-by-step explanation:

A right triangle has one angle that is exactly 90o. 89o will not do. 91o is too far away. It must be 90 with no rounding.

D is the only triangle that fits that description.

the answer is here: : )

:

(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
