they took one from 273 and added it back to the fraction but the fraction is /45 so you would add 45 to 9/45
Hello from MrBillDoesMath!
Answer:
41 sqrt(3)
Discussion:
My first reaction to the problem was:
sqrt(27) = sqrt ( 3 * 9) = 3 sqrt(3) and
sqrt(48) = sqrt (3*16) = 4 sqrt(3).
So...
7 * sqrt(27) + 5 sqrt(48) =
7 * (3 sqrt(3)) + 5 * (4 sqrt(3)) =
21 sqrt(3) + 20 sqrt(3) =
41 sqrt(3)

P.S. I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!
Answer:
see below
Step-by-step explanation:
4xy+ x+ 2xy
Combine like terms which are 4xy and 2xy
6xy+x
Answer:
x>-6
Step-by-step explanation:
The expression you need to solve for this is: 2x+15>3
For now pretend that the > is a = and solve as you normally would for x.
Subtract 15 from both sides
2x=-12
Divide by 2
x=-6
Put the > back in
x>-6
U r going to subtract 3 from each side of the equation....leaving you with :
x^2 + 2x = -3
