A rectangle has a length of x³ - x + 2 and a width of x + x². What is the area of the rectangle when x = 2?
A rectangle has a length of x³ - x + 2 and a width of x + x². What is the area of the rectangle when x = 2?
Explanation
Length = x³ - x + 2
= (2)³ - 2 + 2
= 8 - 2 + 2
= 8
Width = x + x²
= 2 + (2)²
= 2 + 4
= 6
Area = Length * Width
= 8 * 6
= 48
