63/80 x 100 = 78.8%
You divide normally but multiply by 100 (moving the decimal over two places).
The expression can be solved by expanding the bracket and multiplying out the terms


Therefore, the expression can be simplified as;

Alternatively, using the theorem of difference of two squares, which is

Hence,

Answer:

Step-by-step explanation:
1) Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd.

2) Collect like terms.

3) Simplify.

Therefor, the answer is, 10x^3 - 26x^2 - 12x.

Answer:
Step-by-step explanation:
When you find the sum of a number you are adding two or more numbers together. therefore the only answer that you could use to get a sum of 5 when your first term is 12 would be -7
