Let the integers be x and x + 2, provided x is an even value.
The product is six more than 3 times their sum.
x(x + 2) = 6 + 3(x + (x + 2))
By expanding and simplifying, we get:
x² + 2x = 6 + 3(2x + 2)
x² + 2x = 6 + 6x + 6
x² + 2x = 12 + 6x
x² - 4x - 12 = 0
(x - 6)(x + 2) = 0
x = 6 or x = -2.
Thus, your integers are: 6 and 8 or -2 and 0
I'm pretty sure the answer is 90 = n decimal 0.8
Answer:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.
