The speed is 0.25 miles per minute, so if the person goes at a steady speed, its 15 MPH
Answer would be D You can have a rational discriminant for an irrational root, but you can also have rational discriminant for a rational root. So C is partially correct.
<span>All prime discriminants will result in an irrational root, but not all irrational roots have prime discriminants </span>
2x + 40
Divide both sides by 2

Answer:
-(x-8)*(x+7)
Step-by-step explanation:
Use the commutative property
-× to the power of 2 + x+ 56
-x to the power of 2 + 8x-7x+56
-xx(x-8)-7x+56
-x*(x-8)-7(x-8)
factor out -(x-8)
-(x-8)*(x+7)
hope it helps!!
