Rewrite each expression as a polynomial in standard form: x^2-5x+6 ÷ x-3 + x^3-1 ÷ x-1

So in standard form equation will be

Step-by-step explanation:

We have given expression

Let first we solve first part of the expression

So

Now second part

We know the algebraic identity

So by using this identity

Now adding first and second part

So in standard form equation will be

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
