Step-by-step explanation:

The average of the other months is 57.5, giving us 2.5 until 60. 2.5 times 4 is equal to 10. 60 plus 10 is equal to 70

6+2y, since the tree is already 6 feet, it grows 2 feet per year so you add 2 feet to the 6 feet every year

1250 miles. You're given a rate and a time, so you can solve for distance using d =rt
d= 250*5 = 1250

The general form of the quadratic equation is :

$ax^2+bx+c=0$

The discriminant is :

$D=b^2-4\cdot a\cdot c$

And the general solution is :

$x=\frac{-b\pm\sqrt[]{D}}{2\cdot a}$

So, there are 3 situations for D

1. D = 0

So, the roots of a quadratic equation are two similar roots

2. D > 0

so, roots of a quadratic equation are two different roots

3. D < 0

so, roots of a quadratic equation are not real, two comlex roots
