Step-by-step explanation:
Select all of the following that are quadratic equations.
x² + 3x - 5 = 0 ✓
x² - x = 3x + 7 ✓
5x - 7 = 0 X
7x² + 14x = 0 ✓
x³ - 3x² + 1 = 0 X
x - 5 = 9x + 7 X
What is quadratic equations?
Quadratic equations is a equation that has a general form like "ax² + bx = c"
For example :
x² + 3x - 5 = 0
x² + 3x = 5
x² → ax²
3x → bx
5 → c
Answer:
This is B) A reflection over the y-axis.
Step-by-step explanation:
You can tell this in a picture due to the fact that each point on the corresponding triangle is equidistant from the y-axis. Take the point at the bottom for instance. In both pictures, it is 2 spaces away from the y axis.

Answer:
(4p * 4p * 4p * 4p) * (4p * 4p * 4p * 4p)
Step-by-step explanation:
exponent is the number being multiplied by itself a number of times
2^4 is 2*2*2*2
3^1 is 3
I’m pretty sure it’s 11. So answer D
