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:
Area = 5/6 of a foot^2
Step-by-step explanation:
Formula
Area of a trapezoid (formula) = 1/2 (b1 + b2)*h/2
Givens
- b1 = 2 feet
- b2 = 3 feet
- h = 1/3 foot
Solution
Area = 1/2(2 + 3)*1/3
Area = 1/2(5)* 1/3
Area = (1/2 * 1/3) * 5
Area = (1/6) * 5
Area = 5/6
