Answer:

x=0, 3/2, -1, -5/3

Step-by-step explanation:

The x-axis interception points of x(4x-6)(x+1)(3x+5): (0, 0), (3/2, 0), (-1, 0), (-5/3, 0)

The y-axis interception points of x(4x-6)(x+1)(3x+5): (0,0)

So the answer is 0, 3/2, -1, and -5/3.

Answer:

$81.2\:\mathrm{ft}$

Step-by-step explanation:

$\tan33^{\circ}=\frac{h}{125}$ , where $h$ is the height of the tree.

Solving, we get:

$h=125\cdot \tan 33^{\circ},\\h\approx \fbox{$81.2\:\mathrm{ft}$}$ .
