Complete the following statement.

Svetradugi [14.3K]

Answer:

if $p ( x ) = x^2 + 7 x + 3$ is divided by $x + 4$ , the remainder is -9

Step-by-step explanation:

We need to find the remainder if $p ( x ) = x^2 + 7 x + 3$ is divided by $x + 4$

Dividing $p ( x ) = x^2 + 7 x + 3$ by $x + 4$

The division is shown in figure attached.

The remainder = -9

The quotient = x+3

So, if $p ( x ) = x^2 + 7 x + 3$ is divided by $x + 4$ , the remainder is -9

The ratio of the number of Sam's CDs to the number of Alice's CD's is 7 to 8. Sam has 84 CDS.

Alex

Answer:

180 CDs

Step-by-step explanation:

So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
