14
Step-by-step explanation:
8
so the problem is x² +2 (x+3)
so x + 3 is 3 so since x is 3 we multiply the x² so 3 times 2 is 6 and 6 plus the remaining 2 is 8
Answer: 8
no
no,
it is not in the form
28
So this means to replace the r you see in 4r^2-8 with 3.
Let's do that:
4(3)^2-8
Now to simplify this just use pemdas or a calculator:
4(9)-8 since 3^2 means 3*3=9
36-8
