Answer:
25x^2 -40x + 16
Step-by-step explanation:
(5x-4)^2
(5x-4)(5x-4)
FOIL
first 5x*5x =25x^2
outer 5x*-4 = -20x
inner 5x*-4 = -20x
last = -4*-4 = 16
Add them together
25x^2 -20x -20x+ 16
Combine like terms
25x^2 -40x + 16
I think it's 202.5
I multiplied 450 and 45%
and then you're supposed to add them I believe
202.5+450
