Use the FOIL method to multiply these terms. Multiply the first, outside, inside, and last terms:
(5x - 4)(2x - 5)
(5x)(2x) + (5x)(-5) + (-4)(2x) + (-4)(-5)
10x² - 25x - 8x + 20
10x² - 33x + 20
The area of the rectangle should be 10x² - 33x + 20.
4(5)+4(3)+3(2)=$38 total cost =$38
X=14
Step by Step
x+10=2x-4
-x. -x
10=x-4
+4. +4
x=14
