Sum of the number is 8.4
Step-by-step explanation:
x = sum of a number
(5 × x) + 6 =48
5x + 6 = 48
5x + (6 - 6) = (48 - 6)
5x = 42
5x ÷ 5 = 42 ÷ 5
x = 8.4
Let the middle child be x
youngest child = x - 1
Oldest child = x + 1
(x - 1)^2 = 8(x + 1) + 4
x^2 - 2x + 1 = 8x + 8 + 4
x^2 - 10x - 11 = 0
(x - 11) * (x + 1) = 0
X = - 1 makes no sense. How can a middle child be - 1 years old?
x = 11
The youngest child is 10
The middle child is 11
The oldest child is 12
