It's A.

You've got 3 as a coefficient on both sides, so you can divide both sides by 3 to cancel them out. Then you've got:

x + 4 = x - 5

You know that this can't have a solution because there is no value x where if you add 4 to it and subtract 5 from it, you'll get the same thing.

So, the problem with the equation is that the x values have to be the same, but the constant numbers added/subtracted are different.

What are the solutions of 2x2 3x = -5?
Mama L [17]
I'm guessing the equation is 2x^2-3x=-5
If this is the case, then you need to set the equation to equal 0 by moving the -5 to the left side of it
2x^2-3x+5=0
The you can factor the equation
(2x-5)(x+1)=0
now solve for each factor
2x-5=0 is x=5/2x
x+1=0 is x=-1

A regular polygon
olga55 [171]

Answer:

3.6° = ext. angle

Step-by-step explanation:

For the shape to be a regular polygon, all interior angles must be congruent.

We can find every interior angle by using the formula:

\frac{180(n-2)}{n}

\frac{180(100-2)}{100}

\frac{180(98)}{100}

\frac{17640}{100}

176.4 = each int. angle

We also know that int. and ext. angles are supplementary!

180 = 176.4 - x

3.6° = ext. angle
