Answer:
(f-g)(x) = 11x+4
Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
This means we have
3x+10x-(2x-4)
This gives us
3x+10x-2x--4
3x+10x-2x+4
13x-2x+4
11x+4
Answer:
12a+2b
Step-by-step explanation:
1. Expand by distributing terms.
20a-8b-2(4a-5b)20a−8b−2(4a−5b)
2. Expand by distributing terms.
20a-8b-(8a-10b)20a−8b−(8a−10b)
3. Remove parentheses.
20a-8b-8a+10b20a−8b−8a+10b
4.Collect like terms.
(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)
5. Simplify.
12a+2b12a+2b
6.Answer
12a+2b
