f(2) = 18

Option 4 is correct

Step-by-step explanation:

Given: f(x)=3(x+4)

To find: f(2)

The given function is linear function with variable x to find the value of function at x=2

So, put x=2 into the function and simplify it

f(x) = 3(x+4)

f(2) = 3(2+4)

f(2) = 3(6)                 [ multiply 3 and 6 = 18]

f(2) = 16

Hence, The value of f(2) is 18 of the given function.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
