Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
Answer:
63
Step-by-step explanation:
plz brainliest :)
do you want an explanation?
What? what is the question?
48
12 * 4
6 * 2 * 2 * 2
3 * 2 * 2 * 2 * 2
it should be 3 * 2^4...but that is not an answer choice
3 * 2^2 * 4 is ur answer....apparently they didn't factor the 4
Ok so what you're trying to do is get L by itself so to do this you move everything to the other side:
A=L*WH

=L
So you answer would be:
C
