PLZZZ help with this its pretty simple!

see below

Step-by-step explanation:

We want x² - 100.

We are adding these two binomials. Already we should recognize that adding these will not result in x².

–No–

We want to expand the binomial first.

(x - 9)(x - 9) - 19

Multiply using FOIL.

(x² - 9x - 9x + 81) - 19

Simplify.

x² - 18x + 81 - 19

x² - 18x + 62

–No–

Distribute the x.

x² - 100x

–No–

FOIL

x² - 10x + 10x - 100

Simplify.

x² - 100

–Yes–

A. No

B.No

C.No

D.Yes

D is the only one where x results in x^2-100

the homeowners insurance cost for a 115,000 wood frame house is 80,500.
