What are the solution(s) to the quadratic equation 40 - x2 = 0?
x = +2/10
x = +4/10
x = +25
x = +4/5

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
