Answer: f(-12)=-9

Step-by-step explanation:

We have the following function:

f(x)=2x+15

And we have to evaluate it when x=-12, this means we have to substitute x by -12:

f(-12)=2(-12)+15

Solving:

f(-12)=-24+15

Finally:

f(-12)=-9

Factor (2x^2+4x) + (1x+2)
tensa zangetsu [6.8K]

Answer:

(2x + 1) (x + 2)

Step-by-step explanation:

2x² + 4x + 1x + 2

They are already arranged, so you just have to find the GCF. 2x² + 4x  have the GCF of 2 and 1x + 2 have the GCF of 1.

2x (x + 2) + 1(x + 2)

Now you divide the whole thing by x + 2.

2x (x + 2) + 1(x + 2)/ x + 2

One of them cancels out  leaving (2x + 1) and (x+2)
