If that was f(x)=3(x+5)+4 you have:

f(a+2)=3(a+2+5)+4

f(a+2)=3(a+7)+4

f(a+2)=3a+21+4

f(a+2)=3a+25

Not really sure what "f(x)=3(x+5)+4?x" means...

F(a+2)=4a+23, all you have to do is plug in a+2 into x and once you have done that make sure to distribute both quantities.

Kanya is comparing the rate for shipping and handling for two online shopping websites. For the item she has selected, Big Barga
kari74 [83]
Answer:

D. Discount Deals Depot; $15.20

Why?
Lets do Big Bargain Bonanza first.
$8.00 would stay the same as it is for handling. The only number that would change is $1.25, it uses the the words PER pound for shipping.

Your equation would look like this with p being how many pounds Kanya is shipping:
$8.00+$1.25p

Now we just plug in the numbers.
$8.00+$1.25(6)=
$8.00+$7.50=
$15.50

The same games for Discount Deals Depot.
$9.50+$0.95(6)=
$9.50+$5.70=
$15.20

So in conclusion Discount Deals Depot; $15.20 is cheaper than Big Bargain Bonanza;$15.50

Leto [7]

7 shirts

Step-by-step explanation:

First, you’d do 10$ spent on lunch and the 35$ spent on the jeans or pants. You add those together to get 45$. You then subtract that from $134.25. Your answer should be $89.25. Now, divide 89.25 by 12.75 to get 7. 7 shirts!
