Answer:

OC. 5x + 45 + 7y + 14 - X, OE. 4x + 7y + 11

Step-by-step explanation:

Because, 5(x + 9) is 5x + 45 and 7(y + 2) is 7y + 14 and so you simplify by simplifying the like terms for example 5x - x = 4x 45 + 14 = 59 and 7y stays the same.

Use properties of operations to determine whether 4r + 4t and 4(r+t) are equivalent. Explain your answer.

Vikki [24]

There is only one property used to determine whether

$4r+4t=4(r+t)$ .

The property is called the distributive property and in a nutshell it states, $a(b+c)=ab+ac$ , which means $a$ is distributed through $b+c$ using multiplication. So $4(r+t)$ says, distribute $4$ to $r$ and $t$ which then translates into $4r+4t$ .
