Given f(x)=10x+8 and g(x)=1x+4 then what is (f+g)(3)) ?

1 answer:

3 0

f(x)=10x+8

g(x)=1x+4 = x+4

(f+g)(x) = f(x) + g(x) = 10x+8+x+4 = 11x + 12

(f+g)(3)= 11(3) + 12 = 33 + 12 = 45

hope that helps

Answer:

8sin(x)cos³(x)

Step-by-step explanation:

sin(4x) +2 sin(2x) = 2sin(2x)*cos(2x) + 2sin(2x) = 2sin(2x)(cos2x + 1)=

= 2sin(2x)(cos²x - sin²x + cos²x + sin²x)=²2sin(2x)*(2cos²x)=

= 4*2sin(x)*cos(x)*cos²(x)= 8sin(x)cos³(x)
