Answer:
-3
Step-by-step explanation:
To find the average of different numbers, first you add them all up. So -5+-7+-2+2+-3+=-15. Then, you divide the sum of all the numbers by the amount of numbers there were. So in this case, there were 5 numbers so we would divide the sum of all of them by 5. So now we do -15/5=-3.
Another example of finding the average of numbers is 15+4+10+9+3+1. So first we add them up and we get 42, then again, we divide by the amount of numbers there are. So we do 40/6 and we get 7, so the average is 7.
I hope this helped.
Divide -38 by -5
The negatives cancel out since a negative divided by a negative is a positive.
7.6
Answer: (x-12)^2-144
Step-by-step explanation:
use the formula (b/2)^2 in order to create a new term to complete the square.
LET ME KNOW IF ITS RIGHT
Answer:
Option b is correct
Step-by-step explanation:
In order to check the end behavior of a polynomial function we just check the leading term and its coefficient and the procedure is as follows:
Here we can see that highest exponent of the polynomial function is 4
therefore degree of the polynomial is 4. and therefore 
is leading term.
because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of leading is negative therefore it falls at both ends. that is falls to the left and falls to the right.
therefore option b is correct.
Answer:
37 inch
Step-by-step explanation:
Area of ∆ = ½ height x base
210 = ½ x 35 x base
12 = base
Using Pythagoras theorem,
=> hypotenuse = √height² + base²
=> hypotenuse = √35² + 12² = 37
