For #1 you're just plugging in the numbers that are in the parentheses for x.

For example:
f(2)
Take the given equation to plug in for x:

x^2-4x+5

(2)^2-4(2)+5

And from there you get the answer. Your final answer will look like this:

f(2)=? {the answer you got when you plugged in}

A store pays $22 for a duffel bag. The store marks up the price by
fredd [130]
Marks UP the price by 30%.

There's two ways:
30% of $22, plus $22.
OR
130% of $22.

To save time, 130% of 22.

130/100 x 22
= 13/10 x 22
=13/5 x 11
=143/5
= 28.6

$28.6 

Hope this helps!

#5,

it says that the angle on top is 221, so you subtract that from 360,

360-221= the rest..... 139
 Now in that 139, you can see that there is a triangle with a right angle. so you can subtract 90 degrees from 139

139-90= 49
49 is the number you use to solve the rest.
3x + 4x = 7x
so 7x = 49
and then you divide 7 from both sides to isolate x, and you get your answer
