8 0
9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9

In short, Your Answers would be -1 and 9

Hope this helps!

Noah’s age is 3 years more than twice tinas age. the sum of their age is 24. how old are they?
nignag [31]
Answer:
Noah is 17 and Tina is 7.
Why?
Let t represent Tina’s age.
So, 2t + 3 is Noah’s age.
This is your equation;
2t + 3 + t = 24
Now, simplify so t is on one side.
3t = 24 - 3
3t = 21
t = 21/3
t = 7
Tina’s age is 7, and Noah (according to the expression made for him) is 17.
Check:
7 + 17 = 24
