Casey has n nickels. Megan has 4 times as many nickels as Casey has. Write and expression for the total number of nickels Casey
AnnyKZ [126]

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.

\text{Total number of nickels Casey and Megan have}=n+4*n

Therefore, the expression n+4*n will represent the total number of nickels that Casey and Megan have .

Upon combining like terms we will get,

\text{Total number of nickels Casey and Megan have}=(1+4)n

\text{Total number of nickels Casey and Megan have}=5n

Therefore, Casey and Megan have 5n nickels.

Rewrite the equation by completing the square.<br> x^2 -4x =0
olasank [31]

Step-by-step explanation:

x² − 4x = 0

To complete the square, take half of the second coefficient, square it, then add the result to both sides.

(-4/2)² = 4

x² − 4x + 4 = 4

(x − 2)² = 4

x − 2 = ±2

x = 2 ± 2

x = 0 or 4
