Subtract. (−d2 + 12d − 4) − (−7d2 − 2d + 12) =

The answer would be 26d - 16

I am using d^2 instead of d2 as that seems written incorrectly.

Same for -7d^2 instead of -7d2.

Start by changing the signs in the 2nd parenthesis by changing the subtract sign to a plus.

(-d^2 + 12d - 4) + (7d^2 + 2d - 12)

Now combine like terms

(7d^2 - d^2) + (12d + 2d) + -4 + -12

6d^2 + 14d + -16 (or 6d^2 + 14d - 16)

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.
