Answer:  3/5 inches

Step-by-step explanation:

l= 5w+7

A = wl

w(5w+7) = 6

5w²+7w = 6

5w²+7w -6 = 0

5w²+10w-3w-6=0

5w(w+2)-3(w+2)=0

(5w-3)(w+2)=0

5w-3=0            w+2=0

   5w=3                w=-2in

     w=3/5in

width cannot be negative, so the width is 3/5 inches.

Please Help (assignment is attached)
Marat540 [252]

Answer: The formula is I=PRT where I is interest, P is principle, R is rate and T is time. Using these quantities, plugging in the values and solving for R is how to go about the problem.

509.60=910*8*R

509.60/(7280)=R

0.07= R so the interest rate is 7%. Hope that helped!
