Step-by-step explanation:
Let n be the number of nickels that Casey has.
We are told that Megan has 4 times as many nickels as Casey has, therefore, the number of nickels that Megan has will be 4*n.
Now we will add the amounts of nickels that Casey and Megan have to find the total amount of nickels.
Therefore, the expression 
will represent the total number of nickels that Casey and Megan have .
Upon combining like terms we will get,
Therefore, Casey and Megan have 5n nickels.
Answer:
Step-by-step explanation:
The easiest way to solve this equation is to first find and highlight a common factor between two terms. In this case, x^2 can be factored to rewrite the equation as follows:
The (x+7) term can be crossed out on both sides and then for this equation to be true, there are two possibilities:
Either
or
Therefore, the solutions to this equation are -1, 1 or -7.
M(x) * n(x)
= (−2x^2 + 8x−3) * (<span>2x^3−4x)
= -4x^5 + 8x^4 + 16x^3 - 32 x^3 - 6x^2 + 12x
= -4x^5 + 8x^4 - 16x^3 - 6x^2 + 12x

1 is a whole number so it stays before the decimal.
Divide 1 by 4.
1 ÷ 4 = 0.25
Now add the whole number to the fraction.
1 + 0.25 = 1.25
This is not repeating, therefore it is a terminating decimal.
