<span>Algebraic expression of product of 2 and the second
power of y
=> Algebraic expression is a combination of integers (numbers), variables (a,
b, c, x, y, ….), exponent (2 5 3 …) that is a rational number and algebraic
operations like subtraction (-), addition (+), multiplication (x) and division
(/).
=> Product – result of multiplication
=> second power of y = y<span>2
</span>=> 2 x y<span>2
</span>Thus, the algebraic expression of product of 2 and the second power of y
is equals to 2 x y2

Answer: 5x3 + x2 - 2x + 5
Make sure to combine like terms and watch out for if it’s subtraction or addition.
X = a/b
4 = a/2
multiply both sides by 2 to isolate the variable
a = 8
The formula for a cone is pi * r^2 * (h/3) or pi* r^2 * h * 1/3.
Since the height is 7ft and the radius if 4ft you plug those into the equation and get:
V= 1/3 * pi * (4^2) * (7)ft cubed which is the answer of B
