113.25 because the middle ground of 1 - 150 students is 75 and then 1+150=151 2+149+151 but instead of doing that again and again just multiply the lowest number and the highest number by the middle ground
For this case we have the following equation:

Rewriting we have:

Dividing by 2 to both sides of the equation:

We apply the quadratic formula:

We have to:

Substituting:

Thus, we have two roots:

Answer:
A. -12h² - 22h + 14
Step-by-step explanation:
(-4h +2)(3h +7) = -4h(3h +7) +2(3h +7) . . . . . . . (a +b)c = ac +bc
= (-4h)(3h) + (-4h)(7) + (2)(3h) + (2)(7) . . . . . . . a(b +c) = ab +ac . . . (twice)
= -12h² -28h +6h +14
= -12h² -22h +14 . . . . . . . . collect terms
Answer:
y intercept= 0
Step-by-step explanation:
in the formula y=mx+b, m is the slope and b is the y intercept. here we are not given "b" so the y intercept it 0
first pemdas
parentheses exponents multiply divide addition and subtraction
so the answer is 7
