<span>1. 3x^2-8x+5=5x^2
2x^2+8x-5
Discriminant = 64+40 = 104 > 0
The answer is 2</span>
Make the equations equal and solve for x
- 2x²+6x+1=-4x²+1
- 6x²+6x=0
- 6x(x+1)=0
- 6x=0 or x+1=0
- x=0 or x=-1
For x=0
For x=-1
The solutions are

In 4 days, because 5 x 4 = $20
30 + 20 = $50
9 x 4 = $36
36 + 14 = $50
4 was multiplied then added in order to find out Erins, and Andres.
Answer:
39?
Step-by-step explanation:
180-102=78
78/2=39
To determine to measure the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Hope this helps you understand angles in a triangle
