We have to simplify this as a product of fractions. Notice that the 6 has a negative sign, therefore, the result will be negative. We have then:

therefore, the simplified result is -2
Find the domain by finding where the function is defined. The range is the set of values that’s correspond with the domain
This essentially means 12-8
|| means absolute value which is the distance from 0 the number is
Basically it’s the number but positive
So the answer is 4
Answer:
first one: 3 1/3 = 7/3 second: 2 3/4 = 11/4
third one: 3 1/3 + 2 3/4 = 10/3 + 11/4 = 40/12 + 44/12
there fore the answer is: 84/12 or 7
this may help you the first one question only.
The answer is 10
8+(8)2÷4·2
8+16÷4·2 4·2=8 then 16÷8
8+2=10
just use PEMDAS
