If the length of a rectangle is represented by the expression (2x+5) and the width of the rectangle is represented by the expression (3x-1), which expression could be used to represent the area of a rectangle? a.6x²+13x-5
b.6x²-13x-5
c.6x²+17x-5
d.6x²-17x-5

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.
