Hello There!
Before we start, I am going to divide 3.5 by 2 because then we can multiply by 7 to see how far Jimmy can run in 70 minutes.
Jimmy can run 1.75 miles in 10 minutes.
To find out how many miles he can run in 70 minutes, we just multiply 1.75 by 7 and we get a product of 12.25
Jimmy Can Run 12.25 Miles In 70 Minutes
Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : 
Where l is length, w is width, and h is height
Plugging in the new values we get:

The surface area of the enlarged prism = 376 cm^2
Answer:
x=-3
