#1
That is false..one could have side lengths of 9 and 1, and the other could have side lengths of 3. Both the areas would be 9, but the figures would not be congruent.
#2
That is true, they must both have the same side length to have the same perimeter, therefore they will also have the same area.
A(1.3) (3,1) idk if it’s right but seems like the right answer
What is the number line i'm sorry but i can help without a number line that this question is based off of.
Answer:
3
Step-by-step explanation:
We have given
,
and SP =30
We have to find the slope for regression on Y from X
The slope on Y from X is given by 
As we have given the value of SP =30 and value of 
So slope for regression will be
