Answer:
30) A) 0 / 15 = 0
31) A) 0/28 = 0
Step-by-step explanation:
30)
0 / 15 = 0
15/0 undefined
15 + 0 = 15
15 - 0 = 15
Answer:
0 / 15 = 0
31) Answer: A) 0/28 = 0
Given:
Consider the given equation is:

To find:
The missing exponent.
Solution:
Let x be the missing exponent. Then the given equation can be written as

It can be rewritten as:

![[\because a^ma^n=a^{m+n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5Ema%5En%3Da%5E%7Bm%2Bn%7D%5D)
On comparing the coefficient of m, we get



Therefore, the value of the missing exponent is 8. So, the complete equation is

Answer:
D.
Step-by-step explanation:
The formula is Sum(n) = (n -2) 180.
Acute-The angle is less than 90 degrees
Equilateral-All sides are equal in length
Isosceles-Two of the sides are equal in length
Scalene-None of the sides are equal in length
Right-The angle is 90 degrees
Obtuse-The angle is greater than 90 degrees
We can see that none of the sides are the same length, so we know that it must be scalene. We can also see that every angle is less than 90 degrees, so we know that is must be acute.
The triangle is scalene and acute.
Hope this helps!!
