Answer:
1) 8
2) 9
3) 8
4) 12
Step-by-step explanation:
Well, assuming the sides that are numbered are the same length (not sure because no instructions). You have to do is set both equal to each other. An example being:
6 = 2x - 10
16 = 2x
8 = x
And you just do that with the first three problems.
For number 4 set them equal to each other, solve for x and then plug x back into the equation.
2x - 6 = x + 3
x = 9
2(9) - 6 = 18 - 6 = 12
And for number 5 set them equal to each other, solve for x, then plug in x like the previous problem and that's the answer because they are all 90 degree angles.
Answer:
That is, they are equivalent expressions. Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them. Example 1: Are the two expressions 2y+5y−5+8 and 7y+3 equivalent?

Find the Slope
(−1, −2) , (3, −1)
Slope is equal to the change in y over the change in x, or rise over run.
change in y
m = ---------------
change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called r ise).
y2 − y1
m = -----------
x2 − x1
Substitute in the values of x and y into the equation to find the s lope.
m = −1 − (−2)
/3 − (−1)
Simplify the numerator.
Multiply −1 by −2.
m = −1 + 2
/3 − (−1)
Add −1 and 2.
m = 1/3 − (−1)
Simplify the denominator.
Multiply −1 by −1.
m = 1/3 + 1
Add 3 and 1.
m = 1/4
