You have to do the opposite
22-17=5
5x3=15
15+13=28
28/4=7
The answer is 7. You can check this by doing what it says and if it makes 22, it’s correct. (I’ve already checked it) :)
B. The diagonals bisect each other.
Answer:
RS ≈ 5.83 units
Step-by-step explanation:
Calculate RS using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = R(- 3, 1) and (x₂, y₂ ) = S(2, 4)
RS = 
= 
= 
=
≈ 5.83 ( to 3 significant figures )
8 is the answer to your question
Yes it is true! it is true because two different numbers go to the same number, if it was false it would have to be the one number to two different numbers.
Hope that made sense!
