Find the area:
3 ft
8 ft
5 ft
8 ft
3 ft
64 ft^2
88 ft 2
44 ft^2
68 ft 2

Step-by-step explanation:

Area of the figure = area of rectangle + 2 * area of a triangle

Area of rectangle:

length = 8 ft

Width = 5 ft

Area = length * width

        = 8*5

        = 40 sq ft

Area of triangle:

height (h) = 3 ft

Base b = 8 ft

Area = (1/2)*bh

       = 12 sq.ft

Area of the figure = 40 + 2 *12

                              = 40 + 24

                              = 64 sq ft

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

x+14
