Simplified would be 2a+2b
Answer:
Step-by-step explanation:
x+y = 6
y = (6-x)
7x +12y = 52
7x+12(6-x) = 52
7x +72 -12x = 52
-5x = -20
x= 4 4 days at $7 = $28
2 days at $12 = $24
28+24 = 52

You have to use fractions to show your work and I'm not going to do that but just know that it is the answer.
Answer:

Step-by-step explanation:
Hello,
Based on the indication, we can write this polynomial as below, k being a real number that we will have to identify (degree = 3 and we have three zeroes -3, -1, and 2).

We know that the point (1,10) is on the graph of this function, so we can say.

Then the solution is:

Hope this helps.
