Answer:
x^2 -7x-18
Step-by-step explanation:
(x-9)(x+2)
FOIL
first x*x = x^2
outer 2x
inner -9x
last -9*2 =-18
Add together
x^2 +2x-9x-18
Combine like terms
x^2 -7x-18
The drawing which shows two lines that intersect at Point, A is as represented in Choice 1: Top-left corner.

The discount was 48%. The original price was $28.00, but the new price was $14.60.
The equation for the area of a triangle is ½bh or base time height decided by two. So you plug those numbers in: ½18 x 11 = ½198 = 99. The area of the triangle is 99cm².
