Answer: 10
Step-by-step explanation:
3/2c + 23 = 38
1.5c -23 =38
1.5c = 38 - 23
1.5c = 10
c = 15/1.5
c = 10
Answer:
roots are 8 and 11
Step-by-step explanation:
Vieta's theorem tells you the sum of roots in this case* is the opposite of the x-coefficient, so is 19. Their product is the constant term, 88.
It is convenient to search for the roots by considering the factors of 88:
88 = 1·88 = 2·44 = 4·22 = 8·11
Only the latter pair of factors has a sum of 19, so those are the roots we're looking for.
The roots of the equation are 8 and 11.
