Area of rectangle = Length*width
A = 28 so 28 = 4 * height
height = 28/4 = 7
Answer:
x² - 10x + 24
Step-by-step explanation:
(x -4)(x - 6)
To write this in standard form, we need to FOIL the binomials.
FOIL: first – outer – inner – last
F: x • x = x²
O: x • -6 = -6x
I: -4 • x = -4x
L: -4 • -6 = 24
Combine the new terms.
x² - 6x - 4x + 24
Combine like terms.
x² - 10x + 24
This is your polynomial in standard form.
Hope this helps!
