top middle, square, and right triangle. to find perimeter you simply add all of the side lengths :)
W = 1.414213562 (or 2 squared)
x = 2 (because the y gets cancelled out in the first equation)
y = 1 (since 2(1)=2(1))
tell me if i’m right :)
Step 1: write the number as a product, helps visualizing common factors.

I've marked things being repeating, so, group them up

Now you have a common factor again

Extra, if you want to split the first one, you can see it as the difference of

and

which is further split into
Answer: This is a square. All sides are equal and the each angle is 90°
Answer:
B. (15, 19)
Step-by-step explanation:
To check to see if a particular ordered pair is a solution to an equation, use the values for the variables and see if the equation is true.
A. 4/5(0) +7 = 7 ≠ 1
B. 4/5(15) +7 = 19 . . . . . . is a solution
C. 4/5(-5) +7 = 3 ≠ 11
D. 4/5(-2) +7 = 27/5 ≠ 1
