Answer:
If 78 is their grand total, then those 3 consecutive even numbers have to be 24, 26 & 28
So we first minus 6 both sides
7x^2-14x=-6
then we have
A(x^2-2x)=-6
what is A?
hmm (this should be painfully obvous, but if not, here are steps)
7x^2-14x=-6
A(x^2-2x)=-6
7x^2-14x=-6=A(x^2-2x)
7x^2-14x=A(x^2-2x)
undistribute 7
7(x^2-2x)=A(x^2-2x)
divide both sides by (x^2-2x)
7=A
A=7
Answer:
-3b^4 (6b^3 -b-5)
Step-by-step explanation:
Each term is divisible by 3b^4 so we can factor this out
3b^5 + 15b^4-18b^7
3b^4( b+5 -6b^3)
Rewriting the inside term
3b^4 (-6b^3 +b+5)
We can factor out a negative
-3b^4 (6b^3 -b-5)
In order to find the solution you must calculate the mean, or the average by adding the numbers together and dividing by how many numbers there are.
5.5 + -3.6 + 12.8 = 14.7
14.7 ÷ 3 = 4.9
4.9 is Molly's average score.
