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
40 because if you add 1 to each other those sides so you do 9+9 and 11+11 which equals 40 for your perimeter
The triangle was translated 3 units to the right horizontally. (x+3, y)
You can just move one of the points to see how it moved.
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:




176.4 = each int. angle
We also know that int. and ext. angles are supplementary!
180 = 176.4 - x
3.6° = ext. angle
