√(x + 9) - 4 = 1
√(x + 9) - 4 (+4) = 1 (+4)
√(x + 9)(²) = 5(²)
x + 9(-9) = 25(-9)
x = 16
hope this helps
Answer:
Slope = -1
Step-by-step explanation:
m = y^2 - y^1 / x2 - x1
let (x1, y1) = (-3,4) & (x2, y2) = (2,-1)
m = -1-4 / 2-(-3) = -5/5 = -1
Answer:

Step-by-step explanation:
17 + 6 + 2x
23 + 2x
What we can do is set up an algebraic equation.
our variable can me L for Length
3L+4L+5L=90
now all we have to do is solve
12L=90
---- ----
12 12
L=7.5
now multiple each number in the ratio by 7.5 to find out how long each side is
3 times 7.5 is 22.5
4 times 7.5 is 30
5 times 7.5 is 37.5
the side lengths are 22.5, 30, and 37.5
