I'll just factor the above equation.
x² + 18x + 80
x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10 Correct pair
(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80
x+8 = 0
x = -8
x+10 = 0
x = -10
x = -8
(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0
(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0
I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.
Answer:
6+33=39 now we subtract from 100
100-39=61
He won 61 percent of the games
now we multiply 1200*0.61=732
so he won 732 of the 1200 games
Hope This Helps!!
Answer:
incorrect
2 1/2 divided by 3/4
2 1/2 divided by 3/8 = 6 2/3
6
hope that helped i checked it over im positive its correct
