In short, (h o g)(a) is just h(    g(a)    ).

so what we can do is simply get g(a) first and then plug that in h(x).

\bf \begin{cases}
g(x)&=2x\\
h(x)&=x^2+4\\
(h\circ g)(a)&=h(~~g(a)~~)
\end{cases}
\\\\\\
g(a)=2(a)\implies g(a)=2a
\\\\\\
h(~~g(a)~~)\implies h(~~2a~~)=(2a)^2+4
\\\\\\
h(~~2a~~)=(2^2a^2)+4\implies  h(~~2a~~)=4a^2+4

If you multiply a number by 3 and then add 40, the result is the same as if you add 17 to the number and then multiply by 2. Wha
Finger [1]

Answer:

The number is -6

The second operation is -60

Step-by-step explanation:

Let the number be x.

Solving (a): The value of x

Operations 1:

Multiply by 3: 3x

Add 40: 3x + 40

Operations 2:

Add 17: x + 17

Multiply by 2: (x + 17) * 2

To find x, equate both operations.

3x + 40 =  (x + 17) *2

3x + 40 =  2x + 34

Collect like terms

3x - 2x = 34 - 40

x = -6

Solving (b):

Operations:

Subtract 9: x - 9

Multiply by 4: (x - 9) * 4

This gives:

(x - 9) *  4 = (-6 - 9) * 4

(x - 9) *  4 = -15 * 4

(x - 9) *  4 = -60
