Answer:
(a) 
(b) 
(c) 
(d) 
Step-by-step explanation:
We need to simplify the given expressions.
(a)
Consider the given expression is

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

(b)
Consider the given expression is

Using the property of exponent, we get
![[\because (a^m)^n=a^{mn}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%5Em%29%5En%3Da%5E%7Bmn%7D%5D)

(c)
Consider the given expression is

Using the property of exponent, we get
![[\because a^{-n}=\dfrac{1}{a^n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E%7B-n%7D%3D%5Cdfrac%7B1%7D%7Ba%5En%7D%5D)

(d)
Consider the given expression is

Using the property of exponent, we get
![[\because \dfrac{a^m}{a^n}=a^{m-n}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D)

Answer:
A = 2
B = 4
Step-by-step explanation:
To get an infinite number of solutions, both lines should be the same.
This means
A1x+ B1 = A2x + B2
So,
8x−5x+4−x=Ax+B
2x +4 = Ax +B
With this, we know the value of the coefficients
A = 2
B = 4
Umm, where's the question?????
We can't use the distributive property for this sum
Answer:

Step-by-step explanation:
Given
The attached histogram
Required
The average work hours by 20 salespeople
First, we get the total hours worked as follows:


Divide by number of salespeople
