12. Write the following expression in the form ax? +bx+c, where a, b, and c are real number constants. (x+6)(x+5)+(x+6)(x-2)

x=35

Step-by-step explanation: (x+6)(x+5)+(x+6)(x-2) = (x+6) X (2x+3)= 35

((x + 6) • (x + 5)) +  (x + 6) • (x - 2)

Pull out     x+6  

After pulling out, we are left with :

     (x+6) • ( 1  *  (x+5) - (-1)  *  (x-2) ))

  (x + 6) • (2x + 3)=35

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
