Ir x+2 has a value of 5. then which of the following is the value of x(x+2)+3(x+2)? Show the work that leads to your answer.
(1) 30
(3) 15
(2) 25
(4) 10

we are using binomials

the answer is 1)30

Step-by-step explanation:

k = 2

Step-by-step explanation:

5k = 6k + 4 - 6

We can simplify this by solving 4 - 6 (replacing it with -2 !)

5k = 6k - 2

Now we can subtract 5k from both sides.

0 = k - 2

Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.

2 = k

Just reversing it...

k = 2

k = 2
