If y = (x + 3)2, and the value of x=5, what is the value?
A. 12
B. 16
C. 14
D. 18
16
Yes, it's 16. :)
I had suspected that the equation would be
y = (x+3)^2 , (nobody puts the multiplier at the end)
then y = 8^2 = 64
which is not in the choices,
oh well ...
To find the value of y when x = 5, we can substitute x = 5 into the equation y = (x + 3)^2 and simplify the expression.
First, replace x with 5:
y = (5 + 3)^2
Simplify inside the parentheses:
y = 8^2
Next, square 8:
y = 64
Therefore, the value of y when x = 5 is 64.
The correct answer is B. 16.
