If h(x) = x - 7 and g(x) = x2, which expression is equivalent to (gºn(5)?
(5 – 7)2
O (5)²-7
O (5)²(5 – 7)
(5 – 7)x²

Step-by-step explanation:

hello :

(gºh(5) =g(h(5) )

but : h(5) = 5-7=-2

so : (gºh(5) =g(h(5) ) = g(-2 = (-2)² = (5 – 7)2...first  answer

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
