Area=l*w
a=(x+9)(2x-1) <--- Use FOIL
a=2x²-x+18x-9
a=2x²+17x-9
Hope I helped :)
Answer:
Step-by-step explanation:
What you have here is classic right triangle trig. The height of the tower is the height of a right triangle, and the point 50 feet from the base of the tower is the base of the triangle. The angle of elevation is the base angle that is NOT the right angle. The height is opposite the base angle, while the base is adjacent to the angle, so we need the tangent ratio to find the angle. Here's what we have:
When you are looking for a missing angle, you use the inverse of the angle on your calculator. To do this, hit the 2nd button, then tan, and what you see on your screen is
Enter 200/50 (or 4) and hit "enter" to find the missing angle. It comes out to 75.9 so 76 degrees.
The cost to rent the space with measures 18 ft x 16 ft for a year is $62,208
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The area of the space = 18 ft * 16 ft = 288 ft²
The cost per month is $18 per ft² per month, hence:
The cost of rent per year = $18 per ft² per month * 288 ft² * 12 month = $62,208
The cost to rent the space with measures 18 ft x 16 ft for a year is $62,208

Hey! So this is pretty straightforward. You're given all the information already and now you just have to do some calculations.
60 + 30w = 480
You can start by subtracting 60 from both sides
30w = 420
Now you need to get w by itself so you have to divide both sides by 30 and you will end up getting
w = 14!
