(9x^2+8x)-(2x^2+3x)
9x^2+8x-2x^2-3x
7x^2+5x
Answer:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it's less than 0, there are no solutions. If it's equal to 0, there is one solution.

Answer:
A
Step-by-step explanation:
Corresponding angles are angles that you can follow down the transversal and they will land in the same spot on the other parallel line. Look at angle 8. It is the bottom left angle in the group of 4 angles around it. If you slide it to the left it would land right on top of angle 4 which is also in the bottom left of its group of 4 angles.
You can do the same thing taking angle 8 down to angle 12.
X = 6
9/12 = 0.75
6/8 = 0.75
