For f(x) = 3x - 5 and g(x) = x2 + 2, find (f+ g)(x).
O A. x2 + 3x - 7
B. x2 + 3x - 3
C. 3x3 - 3
O D. 3x2 - 30

B

Step-by-step explanation:

note that (f + g)(x) = f(x) + g(x)

f(x) + g(x)

= 3x - 5 + x² + 2 ← collect like terms

= x² + 3x - 3 → B

12cm

the answer is d

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
