113.04 is the answer do u know how to get it
Answer:
the answer should be x= -9 over 11
Step-by-step explanation:
Since we don't have the measurements for the trapezoid, we can't find the exact cost. However, I can explain how to solve the problem.
First, you need to find the the total area of the pool cover. Since it is in the shape of a trapezoid, use the formula below.
A = 0.5(h)(the sum of the bases)
Once you have the area, multiply by 0.79 and you will have the cost.
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²
The fence is triangular and a right triangle.
<h3>Right triangle:</h3>
A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.
c² = a² + b²
17² - 8² = b²
b = 15 ft
AC = 15 ft
perimeter of the triangle = 15 + 8 + 17 = 40 ft
Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²
Therefore,
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²

Answer:
The 27th term is -22
Step-by-step explanation:
So we know 59 is the first term
and for every term, its -3
