Answer:

101.5yd by 101.5yd size of wood

Step-by-step explanation:

Divide the ramp into its constituent shapes:

2 triangles( 3yd by 4.5yd by 5yd)

1st rectangle (the back) 3yd by 11yd

2nd rectangle (the front) 11yd by 5yd

Find the area of the shapes

Area of triangles = 2 * (1/2*b*h) = 2 * (0.5 * 4.5 * 3) = 2 * 6.75 yd² = 13.5yd²

Area of back rectangle= 3 * 11 = 33yd²

Area of front rectangle = 11 * 5 = 55yd²

Find the sum of the areas

13.5yd² + 33yd² + 55yd² = 101.5yd²

Answer: 3x^4+7x^3+7x^2+11x+4

Step-by-step explanation:

(x^2+3x+4)(3x^2-2x+1)

3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4

Collect like terms

3x^4-2x^3+9x^3+x^2-6x^2+12x^2+3x+8x+4

3x^4+7x^3+7x^2+11x+4
