2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
Answer:
c 2
Step-by-step explanation:
h/3 + h/6 =1
Multiply both sides by 6 to eliminate the fractions
6(h/3+h/6) = 1*6
2h +h =6
Combine like terms
3h = 6
Divide by 3
3h/3 = 6/3
h =2
2 hours
Hello,
Your answers and explanations are below.
6 - 5xy
5 times the product of x and y. The product of x and y means to multiply. That is where we get this: xy. 5 times that product is where we add 5 to it and get this: 5xy.
7 - 4x
We get this because we know he gets $4 an hour. We just do not know how many hours he babysat. The hours is X and we multiply that by 4.
8 - 5.5
Take 8.3 and subtract 2.8 to find x. Once we do that we get 5.5, and that is X.
9 - We can't see the problem. It's cut off
Good Luck,

80y² - 5x²
Factorise
5(16y²-x²)
hope this helps
divide out any similar things, in this case, it is 5
put it outside the parenthesis, and leave the leftover inside the parenthesis
hope this helps
Answer:The answer is x = -203.
Step-by-step explanation:
