Answer:
(f+g)(2) = 10
Step-by-step explanation:
f(x)=2x^2+3x
g(x)=x-2
(f+g)(x) will be sum of f(x) and g(x)
(f+g)(x) = 2x^2+3x + x - 2 = 2x^2+4x - 2
we have to find (f+g)(2), for that we will put x = 2
(f+g)(x) = 2x^2+4x - 2
Thus, (f+g)(2) is 10.
Make one side length of the cube s.
V = lwh, but the length, width, and height are all s.
So V = sss, or s^3.
If it has a side length of 2^4, then 2^4 = 16.
V = s^3, or V = 16 times 16 times 16, which = 4096.
Right away, we know that
which means
Then
Let 
and 
. Then
from which we find
You can use the same ideas above to find the trig ratios for 
, starting from the given fact that 
.
Let's simplify step-by-step.
2(x+7)+3(x+1)
Distribute:
=(2)(x)+(2)(7)+(3)(x)+(3)(1)
=2x+14+3x+3
Combine Like Terms:
=2x+14+3x+3
=(2x+3x)+(14+3)
=5x+17
your answer is 5x+17
