Step-by-step explanation:
4x² + 8x − 7 = 0
4x² + 8x = 7
x² + 2x = 7/4
x² + 2x + 1 = 11/4
(x + 1)² = 11/4
x + 1 = ±√(11/4)
x = -1 ± √(11/4)
Answer:
Right Triangle
Step-by-step explanation:
BC is tangent to circle O, and since radius OB is perpendicular to this tangent, then the triangle must have a right angles in it, making it a right triangle.
The triangle could also be scalene, but that is not for sure, meaning it is primarily a right triangle.
You subsitute 11-2y/7 when you do that you get -2 11-2y/7 +3y=29: y=9 isolate y -2 11-2y/ +3y=29 y=9
x= 11-2 . 9/7 x= -1
Y=9 X=-1
