Answer:
(0,0) and (-530,0)
Step-by-step explanation:
If you have to use the quadratic formula, you need to know your A, B, and C values. Your A value is 4, your B is 2120, and your C value, or constant, appears to be zero. Then you need to plug these values into the quadratic formula to get 0 and -530. This would make your roots to be at points (0,0) and (-530,0).
Answer:
Angle B is 45°
Step-by-step explanation:
Since a and b are both of length 20, this is an isosceles right triangle, and the angle opposite side b must be 45°.
Answer:
There is only one solution. x = 2
Step-by-step explanation:
3(x + 2) = 14 - x
3x + 6 = 14 - x
3x + x = 14 - 6
4x = 8
x = 2
<h2><u>
Answer:</u></h2>
To determine to measure of 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.
