find the missing elements as required in the question with the help of heron's formula: a=10m, b=8m, =12 m c=?? ∆ABC=?? ​

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!

well, if you graph the linear equation using intercepts or other methods, and the line is straight, then the equation is linear

there are three prime numbers with only 1 and themselves as factors so i say one is the greatest common factor for all of them.
