Answer:
A: (3x +4)
B: (4x +5y) × (4x -5y)
Step-by-step explanation:
<u>Part A</u>:
Since we know the trinomial is a perfect square, we know the terms of each binomial factor are the square roots of the first and last terms of the trinomial.
9x² +24x +16 = (√(9x²) +√16)² = (3x +4)²
The side of the square is 3x+4.

<u>Part B</u>:
The difference of squares is factored like this:
a²-b² = (a +b)(a -b)
The given area expression is the difference of squares with ...
a = 4x, b = 5y
so, the factorization is ...
16x² -25y² = (4x +5y)(4x -5y)
The dimensions of the rectangle are (4x+5y) by (4x-5y).

Answer: 84
Step-by-step explanation:
The total number of the questions is 9
Possible question is 3
This is combination
Therefore n=9 and r=3
Combination formula=n! / ((n-r)! r!)
9C3=9! /((9-3)! 3!)
=362880 /(6! 3!)
=362880/4320
=84
