Given that f(x) = 9 – 5x and g(x) = x2, find a simplified expression for
g(f(x))

The answer is f(g(x))=x^2-30x+216

May i have brainliest

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

it is true

step-by-step explanation:

all the combinations add up i used   calculator
