Answer: -16n-41

Step-by-step explanation:

first, distribute 2 through the parentheses:

<u>2(-n-3)</u>-7(5+2n) = <u>-2n-6</u>-7(5+2n)

second, distribute 7 through the parenthesis:

-2n-6<u>-7(5+2n) </u>= -2n-6<u>-35-14n</u>

Collect like terms:

<u>-2n</u>-6-35 and <u>-16n</u>-6-35

Calculate the difference:

-2n<u>-6-35</u>-14n = -16n-<u>41</u>

SOLUTION:

<u>-16n-41</u>

615.44 to the nearest hundredth
Leya [2.2K]
When rounding, look to the next place to the right of what you are rounding to... for example if you are rounding to the nearest hundredth, look to the thousandths place to see if the hundredths place rounds up or down. Since your number, 615.44 stops on the hundredths place, the thousandths place is automatically zero, so your number stays the same.
