y = {x}^{3}  - 4 {x}^{2}  - 45x \\ y = x( {x}^{2}  - 4x - 45) \\ y = x(x + 5)(x - 9) \\ x = 0, - 5,9
So, to find our x-intercepts, y must be zero
0 = x \\  \\ 0 = (x + 5) \\  - 5 = x \\  \\ 0 = (x - 9) \\ 9 = x
ANSWER: (0,0) (-5.0) (9,0) are your x-intercepts

The length of a rectangle is 5 m less than twice the width, and the area of the rectangle is 52 m^2. Find the dimensions of the
lys-0071 [83]

length is 8m

Width is 6.5m

<u>Explanation:</u>

Let, width = b

So, length = 2b-5

area = 52m^{2}

We know,

area of rectangle = length X width

So, 52m^{2} = (2b-5) X b

On solving the above equation, we get

Width, b = 6.5m

length, l = 8m
