Step-by-step explanation:
U = (x - 5)
V = y^3
because we follow the rule
(U+V)^2 = U^2 + 2UV + V^2
factor the expression will be
As per given in question, T is mid - point of QP ; so the measures QT and TP are equal.
that is :
Value of x is 6, so correct choice is D
Mean is equal to sum/ number of values
27+3+2+25+5=62
62/5=12.4
Final answer: D, 12.4 years
