What is 15(2x – 3y + 5x) = ?

1 answer:

6 0

Answer: 105x + -45y

Step-by-step explanation: Since there are three terms inside the parentheses in this problem, the 15 distributes through all three terms.

Before distributing however, change the -3y to plus a negative 3y.

So we have 15(2x) + 15(-3y) + 15(5x).

This simplifies to 30x + -45y + 75x.

Now combine like terms to get 105x + -45y.

Gerardo says that a cube with edges that measure 10 centimeters has a volume that is twice as much as a cube with sides that mea

irga5000 [103]

He is wrong.
The 10 inch cube is bigger than the 5 inch cube by 5 cm in EACH DIRECTION.
So, the 10 inch cube should be twice as big in volume by a factor of 2*2*2
=8
Okay let's see.
5 cm cube volume = 5*5*5 = 125 cc
10 cm cube volume = 10 * 10 * 10 = 1,000 cc

1,000 / 125 = 8
