The correct answer is 15.
(2x^2+13x+15)/2x+3=x+5
Use long or synthetic division to solve this problem.
Answer:
C. x = 6, y = –3
Step-by-step explanation:
I just took the test and got it right :)
4^x + 6^x = 9^x
4^x + 6^x - 9^x = 0
2^2x + (2×3)^x - 3^2x = 0
2^2x + 2^x×3^x - 3^2x = 0
(⅔)^2x + (⅔)^x - 1 = 0
let t = ( ⅔)^x
t² + t - 1 = 0
t = (-1+√5 ) / 2
(⅔)^x = (-1+√5 ) / 2
x = Log base ⅔ ((-1+√5 ) / 2 )
x = 1.18681
Answer:
10 and 15
Step-by-step explanation:
let Cairo's age be x then Poppy's age is x + 5 , then
x + x + 5 = 25
2x + 5 = 25 ( subtract 5 from both sides )
2x = 20 ( divide both sides by 2 )
x = 10
That is Cairo is 10 years old and Poppy is 15
