8. The drama club had a car wash as a fundraiser. Members washed x cars at $5
each and y trucks at $8 each. They made
$250. Find the number of each type of
vehicle they washed using the system of
equations:
(x - y = 11
5x + 8y = 250
A 15 cars and 26 trucks
B 22 cars and 33 trucks
C 26 cars and 15 trucks

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
