Step-by-step explanation:

Using the altitude- on- hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse) , so

x² = 4 × (4 + 8) = 4 × 12 = 48 ( take square root of both sides )

x = $\sqrt{48}$ = $\sqrt{16(3)}$ = 4 $\sqrt{3}$ → A

The first step in the process for factoring the trinomial x^2-3x-40 is to

jenyasd209 [6]

(x-8)(x+5)

First thing you do is put the X's into the parentheticals because it is x^2 meaning there are 2 factors with x's. Then, you wonder what factors of -40 could add to get -3. In this case, they are -8 and 5. -8 times 5 is -40 and -8 +5 is -3. Then, you just add -8 and 5 beside the x's in the parentheticals.
