The sides of the triangle are 3x, 4x and 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5
first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm
2n - 1 - -7n + 2 You combine like terms with subtracting
2n - 7n = -5n
-1 - 2 = -3
So -7n + 2 - 2n - 1 = -5n - 3
Answer:
y = 5.5x – 17
Step-by-step explanation:
Slope (m) = ΔY/ΔX=11/2 =5.5
When x=0, y = -17
Answer:
You have to get to a specific level you move levels by answering questions for people!
HOPE THIS HELPED!!!!!!!!!!!!!XDDDDDD
So hmm notice the picture below
that's (0, -3)
now, keep in mind, adjacent is 0, opposite is -3, and hypotenuse, or radius, is 3
and recall
