2n(n + 3) - 5(n + 3) = (2n-5)(n+3)
A. (n + 3) (2n - 5)
Answer: Coin A is $20, coin B is $10
Explanation:
A + B = $30
B = $10
$10 x 2 = $20
A = $20
$20 + $10 = $30
The volume of the complex figure shown in the diagram is 56 m³.

Volume</h3>
Volume is the amount of space occupied by a three dimensional object.
Volume = length * breadth * width
The volume of the big cube = length * breadth * width = 7 * 3 * 4 = 84 m³
The volume of the small cube cut out = length * breadth * width = 4 * 7 * (4 - 3) = 28 m³
Volume of the complex figure = 84 m³ - 28 m³ = 56 m³
The volume of the complex figure shown in the diagram is 56 m³.
