In classical mechanics there are three base dimensions. length is one of them. what are the other two?

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4
