Answer: 2x^2 + 7x + 2

Step-by-step explanation:

(3x^2 + 5) + (4x-2) - (x^2 - 3x + 1)

distribute the signs to the equations. subtraction on the last one is a little tricky because it turns all of the signs opposite. all subtraction in these kinds of problems is like this so you might want to watch out for this in the future. (:

distribute the signs to get:

3x^2 + 5 + 4x - 2 - x^2 + 3x - 1

simplify the equation. get all like variables together to get:

2x^2 + 7x + 2

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let d represent the distance from the base of the telephone pole to Curtis, hence:

tan(51.4) = (24 - 5.2) / d

d = 15 feet

The distance from the base of the telephone pole to Curtis is about 15 feet.
