From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
This is a difference of squares, meaning that when you multiply the binomials it would be the front term squared minus the last term squared.
The front term squared = (3A) squared = 9A squared
The last term squared = (4B) squared = 16B squared
Final Answer: D. 9A squared - 16B squared

Answer:
- f(x²) = x² +5
- (f(x))² = x² +10x +25
Step-by-step explanation:
Put the argument in place of x and evaluate the desired expression.
__
1. f(x²) = x² + 5 . . . . . . straight substitution for x
__
2. (f(x))² = (x +5)²
= (x +5)(x +5) = x(x +5) +5(x +5) = x² +5x +5x +25
(f(x))² = x² +10x +25
