Answer:
a = 10
Hope this helps :)
a=10
Step-by-step explanation:
5+4a=45
take 5 from each side
4a=40
divide both sides by 4
18x-3
f(x)= 3x + 10x
g(x)=5x - 3
f(x)+g(x) = 3x + 10x + 5x - 3
Combine like terms
= 18x -3
All cubes are similar because every one of them have an equal width and length and height.
I really hope I helped
