2x² - 3x - 20
40
2 20
4 10
5 8
2x² - 8x 5x - 20
2x(x - 4) 5(x - 4)
(2x + 5) (x - 4)
2x + 5 = 0 x - 4 = 0
2x = -5 x = 4
x = -5/2
C) x = -2.5 and 4
Let s be the son's age 15 yeasr ago and m the mother's age that year.
We also know that:
Plotting vallues:
Remember that they were that age 15 years ago.
So their actual age is 30 and 60.

P = 2(l+w)
Step-by-step explanation:
Answer:
y=3
Step-by-step explanation:
perpendicular line to Y-axis passing through any point (m,n) is of the form
y=n
so the answer is
y=3
64-40= 24. Play offense
24:40
Simplify both sides by dividing by 8
= 3:5
