Answer:

$\large\boxed{x=-\dfrac{7}{5}=-1.4}$

Step-by-step explanation:

$\dfrac{1}{3}(5x+1)=-2\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{1}{3\!\!\!\!\diagup_1}(5x+1)=(3)(-2)\\\\5x+1=-6\qquad\text{subtract 1 from both sides}\\\\5x+1-1=-6-1\\\\5x=-7\qquad\text{divide both sides by 5}\\\\\dfrac{5x}{5}=\dfrac{-7}{5}\\\\x=-\dfrac{7}{5}$

Just help me out with this polynomial i need help <br> { -m^{2} + 6} + { -4m^{2} + 7m + 2} =

PolarNik [594]

Answer:

$-5m^2+7m+8$

Step-by-step explanation:

Here, we add up two polynomials shown.

The polynomials are:

$[-m^2 + 6]+[-4m^2 +7m + 2]$

In order to add up the 2 polynomials shown, we have to see the "like terms" and add them up.

We add up the " $m^2$ " terms and the constant (number) terms. There is one term with "m", so we leave it like that. Let's add up. Shown below:\

$[-m^2 + 6]+[-4m^2 +7m + 2]\\=-m^2-4m^2+6+2+7m\\=-5m^2+7m+8$

This is the sum of the 2 polynomials shown: $-5m^2+7m+8$
