So,

2. Find the GCF of 13 and 52:

So,

3. Find the GCF of 15 and 81:

So,

4. Find the GCF of 64 and 28:

So,

Answer:
x = 19 cm
Step-by-step explanation:
perimeter = 46 = 2(x + 4)
2x + 8 = 46
2x = 38
x = 19
Answer:
Y= -4 :)
Steps:
Apply rule
-y + 3 = 7
Subtract 3 from both sides
-y + 3 - 3 = 7 - 3
Simplify
-y = 4
Divide both sides by -1
-y/-1 = 4/-1
Simplify
y = -4

Answer: 1</h3>
========================================================
Explanation:
Pick any two points you want from the blue line. I'll pick (0,1) and (1,2)
Apply the slope formula to those points
m = (y2-y1)/(x2-x1)
m = (2-1)/(1-0)
m = 1/1
m = 1
The slope is 1.
Notice how if we're at (0,1), then we move up 1 and over to the right 1 to arrive at (1,2).
slope = rise/run = 1/1
rise = 1, run = 1
