40need will mark and if you can show your work so that i will know how to do it for future problems that would be : )

A is located at (0,0)

A' is located at (5,2)

Distance (Length) = √((x2-x1)^2 +(y2-y1)^2)

= √(5-0^2) + (2-0^2)

= √5^2 + 2^2

= √25 +4

=√29 ( Exact) or 5.385 as a decimal and round the answer as needed.

The problem doesn't say if the answer was needed as a decimal or not.

Look at the picture.

Use the Pythagorean theorem:

g

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
