Answer:
Step-by-step explanation:
3xy +2m +9 -xy +3m -4
add and subtract like terms
=3xy-xy+2m+3m+9-4
=2xy+5m+5
Answer:
Step-by-step explanation:
40%, assuming that everyone who didn't say they preferred walking preferred running.
4(2x-3) distribute the 4 to expand the expression
8x-12
I assume you mean to find (a) the GCF (greatest common factor) and (b) the least common multiple LCM.
To do both parts, you need ot factor the polynomials.
x^2 - 3x + 2 = (x - 2)(x - 1)
x^2 - 4x + 4 = (x - 2)(x - 2) = (x - 2)^2
(a) GCF: use only common factors with lower exponent.
The GCF is x - 2
(b) LCM: use common and not common factors with the larger exponent.
The LCM is (x - 2)^2(x - 1)
