9. Workpad

Hal is correct!!!! TY

He is just putting workpad meaning that you will have to do it yourself. You should know that already.

HAL TYSM

1. a^2 +b^2 = c^2

9^2 + 12^2 = c^2

81 + 144 = c^2

225 = c^2

sqrt(225) = sqrt (c^2)


c = 15

2. 5^2 +b^2 = 13^2

25 + b^2 = 169

25-25 + b^2 = 169-25

b^2 = 144

b= 12

3. Q
15^2 +20^2 = c^2

225 +400 =c^2

625 = c^2

c = 25

4. Sqrt (4-(-2)^2 + (-6-2)^2))
Sqrt (36 + 64)

= 10

There is no "tagging" or "hashtagging" on Jiskha, thank goodness!!

And you should watch the time. You posted at 2:23 am!! ~ This website is set for Eastern (US) time, and most of the tutors are in either Eastern or Central time zones.

he was saying that because some classes have a essay question others have a abcd question
