Hey! First of all, you can express x squared as x^2.
Secondly, the problem! I'm assuming you're asking for the values of x - if you're asking what the equation is, it's a quadratic equation, or a second-degree polynomial. Solving for x, this equation can be factored as (x-4)(x+1)=0. Because either of these two terms being zero will make the whole equation zero, we can have x-4=0, in which case x=4, or x+1=0, in which case x=-1. Therefore, x is either 4 or -1
7/1 x 3/14 = 21/14 = 3/2 = 1 1/2
The answer is 1 1/12 or 1.5, but I recommend the fraction way since the problem was in fractions!
The length of the support post is 40 ft.
<u>Solution:</u>
Given, the height of the wall is 20 ft; support post forms 30 degree
Refer the attached image
Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and 
is 30 degree (
) and AC is the length of the post.
To find: The length of the post (AC)
we know the formula, 
(trigonometric formula)
On substituting the values we get,
The value of sin 30 degree is 0.5
you want 8 2/3 divided by 1 1/5 =
26/3 / 6/5
= 26/3 * 5/6 = 130 / 18
