Answer:
0.84
Step-by-step explanation:
Divide 63 by 75 and you get 0.84 (84%).
The answer is

first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms

this gives you 3x^2, then you multiple the outer terms

this gives you -21x, then you multiply the inner terms

that gives you 14, now you combine like terms

now you put all the terms together and end up with your solution
