Answer:
A. x-6
Step-by-step explanation:
The area of a square is given by the expression 
square inches. Now we need to find an expression that represents the length of one side of the square, in inches. To do that we need to factor .
Since area of square is given by (side)^2
Hence one side of square is (x-6).
So choice A. x-6 is correct.
Supplementary angles must add to 180 degrees. Let x and y be the measure of the two angles.
y= 6x+5
x+y=180
Substitute y
x+6x+5=180
7x+5=180
7x=175
x=25
Plug the value of x in
25+y=180
y=155
Final answer: 155 degrees
Answer:
f(-3) = -9
Step-by-step explanation:
We want to know what is the y value when x =-3
The value of the parabola is -9 when x =-3
f(-3) = -9
It's just going to require more work but eventually it will solve out, just treat it as if it was just two.
