a 104 square ft room and a 130 square ft room share a wall. what is the greatest possible integer length of the shared wall

1 answer:

6 0

Since the area of a room is its length times its width, you'll need to find a common width, which will be the greatest common factor. The greatest common factor of 130 and 140 is 10. So the shared wall can at most be 10 ft. long.

Name the property of real numbers illustrated by the equation.

Julli [10]

Answer:

Distributive property

Step-by-step explanation:

The distributive property states a(b+c)=a*b+a*c. This property states that when you multiply more than one thing, you must be sure to multiply everything. When you order fast food combos, you do the distribution property to receive the correct order.

If I order 3 Happy Meals, then I will receive

3(hamburgers +fries + drinks +toys)

3 hamburgers+3 fries+3 drinks+3 toys.

If I don't, then I have broken the distribution property.
