Identify the factors of the terms of the expression.  6 + 4a  + 18b  the factors of the terms are 

Factor 2 out of 6+4a+18b

2(3+2a+9b)

term

Step-by-step explanation:

Lets use the letter C to represent cats and D to represent dogs.

A)     2.35c + 5.50d = 89.50

For B, they give you numbers to plug into your equation.
c = 8
d= 14

B) 2.35(8) + 5.50(14) = 89.50
     18.80 + 77.00 = 95.80

So what Pat said is incorrect because that would mean they spent more than 89.50.

Hope this helps! :)
