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

DerKrebs [107]

Answer:

n²-7n-21

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

First, open the brackets:

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

Next, bring the like terms together and simplify:

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

Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)

dlinn [17]

Use the formula slope= y-y/x-x
-10-r/-2-8= 1/10
-10-r/-10= 1/10
Multiply the denominator (-10) on both sides
-10-r= -1
Add -10 to both sides
-r= 9
r= -9
Hope this helps!
