Answer:
15. t = 312
16. y = 0
17. n = -1.75 and 0
Step-by-step explanation:
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 answer to your question is the second option
Step-by-step explanation:
Process
Simplify using exponents laws, first inside the parentheses and then outside the parentheses.
![[\frac{a^{-2}b^{2}}{a^{2}b^{-1}} ]^{-3}](https://tex.z-dn.net/?f=%5B%5Cfrac%7Ba%5E%7B-2%7Db%5E%7B2%7D%7D%7Ba%5E%7B2%7Db%5E%7B-1%7D%7D%20%5D%5E%7B-3%7D)
a) Simplify a
a⁻² a⁻² = a⁻⁴
b) Simplify b
b² b¹ = b³
c) Write the result
![[\frac{b^{3}}{a^{4}}]^{-3}](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bb%5E%7B3%7D%7D%7Ba%5E%7B4%7D%7D%5D%5E%7B-3%7D)
d) ![[\frac{a^{4}}{b^{3}}]^{3}](https://tex.z-dn.net/?f=%5B%5Cfrac%7Ba%5E%7B4%7D%7D%7Bb%5E%7B3%7D%7D%5D%5E%7B3%7D)
e) Simplify
f) Result
<span>draw out a triangle and then create three boxes inside by drawing a T. In each of the boxes you've created you need to put one of the letters from the equation. The equation you currently have is F= m*a. To rearrange this equation put the m and the a into the bottom boxes and the F above. Because there is a vertical line between the m and the a, this means you times them. If there is a horizonal line between two letters you divide them. So to find a, you must divide F by m. </span>
For this case we have the following expression:
We must simplify taking into account that:
So, we have:
We add similar terms:
