Step-by-step explanation:
Answer:
![(x+3\sqrt{2})(x-3\sqrt{2})](https://tex.z-dn.net/?f=%28x%2B3%5Csqrt%7B2%7D%29%28x-3%5Csqrt%7B2%7D%29)
Step-by-step explanation:
The given expression is
.
The technique that can be used to factor this polynomial is the difference of two squares.
We rewrite the two expressions as;
![x^2-(\sqrt{18})^2](https://tex.z-dn.net/?f=x%5E2-%28%5Csqrt%7B18%7D%29%5E2)
Recall that;
![a^2-b^2=(a+b)(a-b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29)
![x^2-(\sqrt{18})^2=(x+\sqrt{18})(x-\sqrt{18})](https://tex.z-dn.net/?f=x%5E2-%28%5Csqrt%7B18%7D%29%5E2%3D%28x%2B%5Csqrt%7B18%7D%29%28x-%5Csqrt%7B18%7D%29)
![x^2-(\sqrt{18})^2=(x+3\sqrt{2})(x-3\sqrt{2})](https://tex.z-dn.net/?f=x%5E2-%28%5Csqrt%7B18%7D%29%5E2%3D%28x%2B3%5Csqrt%7B2%7D%29%28x-3%5Csqrt%7B2%7D%29)
Marcella would not be able to win the competition because her kite string (159.75 feet) is less than 162 feet.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let l represent the length of the string, hence:
sin(28) = 75/l
l = 159.75 feet
