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
HOPE it helps!!!!!!!
plz mark as a brainliest answer!!!!!
3(2t+5)=5t+25
Multiply the bracket with 3
(3)(2t)(3)(5)=5t+25
6t+15=5t+25
Move 5t to the other side. Sign changes from +5t to -5t
6t-5t+15=5t-5t+25
6t-5t+15=25
Move +15 to the other side. Sign changes from +15 to -15
6t-5t+15-15=25-15
6t-5t=10
1t=10
divide by 1
1/1t=10/t
t=10
Answer: t=10
