Hello from MrBillDoesMath!

Answer:

m^2 + 11m - 11, which is the first choice

Discussion:

6m + (m-2)(m+7) +3 =

6m + (m^2 + 7m - 2m -14) + 3 =

(6m + 7m - 2m) + m^2 + (-14 + 3) = combine similar terms

11m + m^2 -11 =

m^2 + 11m - 11

which is the first choice

Thank you,

MrB

First, combine like terms.
2x + 3x can combine into 5x
5x = 5
Divide both sides by 5, and you’ll get a final answer of x = 1.

Answer:

the norm of V = =11.357816691601..

Step-by-step explanation:

$\left\vert \overrightarrow{V} \right\vert =\sqrt{\left( -8\right)^{2} +\left( 7\right)^{2} +\left( 4\right)^{2} }$

$=\sqrt{64+49+16}$

$=\sqrt{129}$
