Answer:

g(f(x)) = gof(x) =( x - 7)^{2}  \\  =  {x}^{2}  - 14x + 49 \\ g(f(4) )\times g(f(4)) = (4^{2}  - 14 \times 4 + 49 )\times( 4 ^{2}  - 14 \times 4 + 49) \\  = 9 \times 9 \\  = 81

jasenka [17]
Hey there!

Your question states:

 <span>John's monthly paycheck consists of $4000 plus a 9% commission on all of his sales. During one month, John earned $11,650. What were his sales during that month?
</span>
We don't want to 9% to really trick us.

We just do 11,650 - 4,000 = 7,650.

Now, we can adjust everything.

That 9% of the commission on the sales was worth . . . 

7,650

Your correct and clarified answer would be . . .

\boxed{\boxed{\boxed{7,650}}}

Hope this helps.

Sue Shopper received a $749.25 discount loan to purchase a refrigerator. The loan was offered at 12% for 120 days
STALIN [3.7K]
The interest paid for the loan will be:
I=(PRT)/100
P=$749.25
R=12%
T=120 days=120/30=4 months=1/3 years
Hence:
I=(749.25×1/3×12)/100
I=$29.97

The proceeds will be:
Net proceeds=(gross proceeds)-(expenses)
=749.25-29.97
=$719.28

Find the perimeter of the figure shown to the right.
tia_tia [17]

Step-by-step explanation:

that is very simple. you do understand the word "perimeter" ? it just means the distance when walking around the whole shape once.

and that clearly means to just add all side lengths.

that's it.

so, 25 + 18 + 18 + 20 + 17 = 98 ft

was there any other problem with this you did not understand ?
