R/ r+ 15 = 3/8
Cross multiply: top of one side multiplied by bottom of other side:
R x 8 = 3 x r+ 15
Simplify:
8r = 3r + 45
Subtract 3r from both sides:
5r = 45
Divide both sides by 5:
R = 9
252 would be the LMC of 63 and 84
Should be 18x^4-12x.

Answer:



Step-by-step explanation:

This means:
- when x is equal to zero or less than zero, g(x) will always be 7.
- when x is more than zero, g(x) is
