3) Check work.
This statement is true.
4) Write equation.

Answer:
x = 4
Step-by-step explanation:
11x= 6x +20
-6x -6x
(subtract 6x from both sides)
5x = 20
/5x /5x
divide 5x from both sides
x=4
Answer:
30
Step-by-step explanation:
there are 3 parts to form that 90 degree angle
K = s + 4
k + s = 26
s + 4 = 26
Subtract 4 from both sides of the equation.
s = 22

We have a point and a slope, so let's use the point slope formula!

where
x1=4
y1=2
and m=3
