Perform the indicated operations(7n^2 - 6) - (6n^2 + 9) - (7n + 6)

DerKrebs [107]

Answer:

n²-7n-21

Explanation:

Given the expression:

$\mleft(7n^2-6\mright)-(6n^2+9)-(7n+6)$

First, open the brackets:

$=7n^2-6-6n^2-9-7n-6$

Next, bring the like terms together and simplify:

$\begin{gathered} =7n^2-6n^2-7n-6-9-6 \\ =n^2-7n-21 \end{gathered}$

Please help me please I can't figure this out!!!!!

Lena [83]

Um...thats a tough one... well first you have to put the formula together which is pi(10)(26)+pi(10)^2 multiply 10 times 26 then 10 times ten giving us a much more easier equation 260pi + 100pi. we can cross off answer A and answer C just by looking at the simplified equation. now add the two together, giving us 360pi inches^2
