Answer:

(2x +3  )(x-5)

one is the length and one is the width

Step-by-step explanation:

2x^2-7x-15

Factor

(2x      )(x      )

What are the factors of -15?  -1*15  and -3*5, 3*-5 , 1*-15

We need 2* one factor ± the other factor = -7

2*-5 +3 = -7

That means the -5 is on the outside and the +3 is on the inside

(2x +3  )(x-5)

For example, if it takes 15 hours to travel 900 miles. How many miles will you travel in one hour?
dalvyx [7]

Answer:

60 miles

Step-by-step explanation:

If it takes 15 hours to travel 900 miles then it gives you the fraction 15/900 where the numerator(top number) is 15 and denominator(bottom number) is 900.

Then to simplify it: since 15 is a common factor of itself(15) and 900, 15/15 = 1(1 hour) and 900/15 = 60(60 miles).

Amelia and 2 of her friends went out to lunch. Each girl ordered exactly the same meal. The total cost was $55.08,which included
Murrr4er [49]
Possibly $16.89 because you multiply 55.08 and .08 to find 4.41 then you subtract that to 55.08 to find the total cost without tax which is 50.67. Then you divide by 3 because there are 3 girls to 16.89.
