X^2 + x(x - 5) - x + 7
x^2 + x^2 - 5x - x + 7
2x^2 - 6x + 7
Given:
13/8
First you have to see how many times 8 can go into the number 13. If you look, 8 can only go into 13 one time, leaving 5 left over.
13-8 = 5
1 with 5 left over
(Rather than writing 8/8, you must simplify to 1 to make it less redundant)
Since there is 5 left over from 8, you would then place it into the numerator place to get:
1 5/8
I hope this helps!
The value of the 8 is 800000
Equations A may be used to determine the lighthouse's height. The best choice is A.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon. It is one of the most fundamental geometric forms.
Given;
(d) 115 meters separate the boat from the lighthouse.
42" is the angle of elevation.
Height is h
Apply the tangent formula in the obtained triangle;

The calculations will determine the lighthouse's height as;

Hence the best choice is A.
