I dont get the question so im going to show you both solutions
if you’re asking for (2m+5)²=0 then
(2m+5)²=0 /√
2m+5=0
m=-5/2

if you’re asking only for (2m+5)² then
4m²+20m+25

Write an equation in standard form of the line that contains the point (-1,2) amd is perpendicular to y = 3x - 1

Strike441 [17]

Since it is perpendicular to y=3x-1, the slope must be a negative reciprocal.
there the slope of the perpendicular line is $-\frac{1}{3} x$

So now we have,
$y=- \frac{1}{3} x+b$

To find b, we use the point that the line passes through and substitute it to the y and x values.

$2=- \frac{1}{3} (-1)+b$

which would give us b=5/3

Therefore, the equation of the line is
$y=- \frac{1}{3} x+ \frac{5}{3}$

Simplify the expression <br><br> 6(-5n + 7)

Hunter-Best [27]

6(-5n+7)=0

We simplify the equation to the form, which is simple to understand

6(-5n+7)=0

Reorder the terms in parentheses

+(-30n+42)=0

Remove unnecessary parentheses

-30n+42=0

We move all terms containing n to the left and all other terms to the right.

-30n=0-42

We simplify left and right side of the equation.

-30n=-42

We divide both sides of the equation by -30 to get n.

n=1.4

Hope this helps!
