Marcelo jogs at a speed of 7 miles per hour when there are no hills. He plans to jog up a mountain road which will cause his speed to decrease by
miles per hour. Which of the following expressions represents the time, t,
in hours it will take him to jog 13 miles up the mountain road?

40 i don’t know lololol

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
