Answer:

x² + x - 30

Step-by-step explanation:

Given

(x - 5)(x + 6)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 6) - 5(x + 6) ← distribute both parenthesis

x² + 6x - 5x - 30 ← collect like terms

= x² + x - 30

I just learned this today and it’s a little confusing , is there anyone that could explain how to do these problems for me ?
evablogger [386]

Step-by-step explanation:

I'll do the first problem as an example.

∠P and ∠H both have one mark.  That means they're congruent.

∠T and ∠G both have two marks.  So they're congruent.

∠W and ∠D both have three marks.  So they're congruent.

So we can write a congruence statement:

ΔPTW ≅ ΔHGD

We can write more congruence statements by rearranging the letter, provided that corresponding pairs have the same position (P is in the same place as H, etc.).  For example:

ΔWPT ≅ ΔDHG

ΔTWP ≅ ΔGDH
