Distribute sum groups
x(x^2 + 4x - 2) - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - 5(x^2 + 4x - 2)
Distribute
x^3 + 4x^2 - 2x - (5x^2 + 20x - 10)
Simplify brackets
x^3 + 4x^2 - 2x - 5x^2 - 20x + 10
Collect like terms
x^3 + (4x^2 - 5x^2) + (-2x - 20x) + 10
Simplify
<u>x^3 - x^2 - 22x + 10</u>

Answer:
Step-by-step explanation:
18y -30 -7y =25
solution
18y -30 -7y =25
so we take like terms that is unknown to unknown whole number to whole number or you can put it this way to remember(brothers go to brothers are the ones with an alphabet , sisters go to sisters they are the ones without an alphabet numbers)......okay lets continue
18y -7y=25+30
when a negative is crossing an equal sign it turns positive and vice versa
so lets solve
11y=55
the one with the unknown will divide
11y/11=y
you cant say 1y its wrong in maths you can say in another subject but not maths....okay...so we say y the 1 is invisible but you can say 2y ,3y etc
Then 55/11=5
so y=5
Thats the correct answer....

Answer:
48%
Step-by-step explanation:
This is a very simple problem of finding percentage.
To find percentage of people preferring pizza, we need to divide "number of person who like pizza" by the "total number of person".
So, that's
240/500
And then we need to multiply by 100 and tag a "%" sign at the end. So let's do this:
So 48% of the people chose pizza.
