Answer: 23

Step-by-step explanation: You can start by setting this up as an equation like so,

X + 3(X) =92 where x is Thomas’ age and the 3x indicates Hullans age being 3 times greater than Thomas.

Combine the x’s

4(x) = 92

Divide by 4 X = 92/4

92/4 = 23, x = 23

Given the functions f(x) = 2x + 5 and g(x) = x2 + 8, which of the following functions represents f(g(x)] correctly?

lakkis [162]

Answer:

Choice 4.

Step-by-step explanation:

f(g(x))

Replace g(x) with x^2+8 since g(x)=x^2+8.

f(g(x))

f(x^2+8)

Replace old input,x, in f with new input, (x^2+8).

f(g(x))

f(x^2+8)

2(x^2+8)+5

Distribute:

f(g(x))

f(x^2+8)

2(x^2+8)+5

2x^2+16+5

Combine like terms:

f(g(x))

f(x^2+8)

2(x^2+8)+5

2x^2+16+5

2x^2+21

Answer:

B. 4200

Step-by-step explanation:

A suitable calculator can add the terms for you. (See attached)

The first term is 69, and the common difference is 75-69 = 6. The general term is ...

an = a1 +d(n -1)

an = 69 +6(n -1)

Then the 28th term is ...

a28 = 69 +6(27) = 231

The average term is (a28 +a1)/2 = (231 +69)/2 = 150.

The sum is the number of terms multiplied by the average term:

sum = 28×150= 4200
