Answer:
Step-by-step explanation:
Given equation:
On comparing the equation by ax² + bx + x = 0, We get: a = 1, b = 2 and c = 3
To Find the nature of the roots of the equation firstly we need to find the discriminant of the equation. The expression b²- 4ac is called the discriminant.
- Two Distinct real roots, if b² - 4ac > 0
- Two equal real roots, if b² - 4ac = 0
- No real roots, if b² - 4ac < 0
The discriminant is smaller than 0.
- <u>Hence, Equation has no </u><u>real</u><u> roots (no solution)</u>
Same-side interior angles are supplementary, meaning that they add up to 180 degrees.
5x + 34 + 2x + 76 = 180
7x + 110 = 180
7x = 70
x = 10
Measure of angle A = 5(10) + 34 = 84 degrees
Hope this helps!! :)
(4x2 – 4x – 7)(x + 3)
(4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3)
4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3)
4x3 – 4x2 – 7x + 12x2 – 12x – 21
4x3 – 4x2 + 12x2 – 7x – 12x – 21
4x3 + 8x2 – 19x – 21
3=-2+B. +2 +3 B=5 “y=1/3x+5” in perpendicular lines slope1times slope 2 creates a negative (-1) example(-3/1)(1/3)=-1 so slope 1 multiplied by slope 2 is the opposite inverse which creates a negative 1
