Part 1:
The length of a side is 9 cm.
The square root of 81 is 9. We have to find the square root bc we know it is a square.
Part 2:
The hypotenuse (or diagonal) is c.
Using the Pythagorean Theorem

you would know that 9 is a and b.

We know that

so you add 81 to 81.

81 and 81 make 162.
So you know ...

You take the square root of 162.

well almost.
You can write your answer as

or

Answer:15
Step-by-step explanation:
answer to a division problem is what quotient means
Answer:
No
Step-by-step explanation:
Based on the table, it would not have been from a linear function. To have a linear function, the x and y values would have to be increasing/decreasing at a constant rate.
This is the change from the first (x, y) pair to the second. Now, let's see if the next has the same change:
-7+4=-3
4-3=1
-3+4=1
3-2=1
Now, let's check the last one:
1+6=7
2-1=1
The y value is still changing by -1, but the x value has been increased by a different amount, therefore it is NOT a linear function.
