Answer:
Step-by-step explanation:
I don't know what level math you're taking but in lower level math this would be undefined, can't be simplified. But some higher levels simplify it with imaginary or complex number representations. So take your pick, but it's still undefined
Use the distributive property to multiply 0.25 by x−6.
combine 
and 0.25x to get x.
Add −1.5 and 28.4 to get 26.9.

True.
The absolute value of anything is the distance that value is away from zero.
For instance, |-5 + 1| = 4
As we can see, any number that we plug into this equation will always be a number equal to or greater than zero.
The simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
According to the question,
We have the following information:
Dave has one $20 bill, three $10 bills, and the same number of $5 bills and $1 bills in his pocket.
The number of $5 and $1 bills are n.
a) So, we will have the following expression for the total money he has:
1*20+3*10+5n+n
20+30+5n+n
Now, adding the numbers together and the terms with the same variable together:
$(6n+50)
b) Now, when n = 5:
$(6*5+50)
$(30+50)
$80
Hence, the simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.

Answer:
4.
A = arcsin(BC/AB) = arcsin(4/10) = ~23.58 deg
B = arccos(BC/AB) = arccos(4/10)= ~66.42 deg
AC = sqrt(AB^2-BC^2) = sqrt(10^2-4^2) = 9.16
5.
A = 90-B=90-20 =70
AB = AC/sinC = 30/sin(20deg) = ~87.71
BC = sqrt(AB^2-AC^2) = sqrt(87.71^2-30^2) = ~82.42
6.
AB = AC/cosA =125/cos(50deg) = ~194.46
B = 90-A = 90-50 =40
BC = sqrt(AB^2-AC^2) = sqrt(194.46^2-125^2) = ~148.96
7.
AB = AC/cosA =8/cos(20deg) = ~8.51
B=90-A =90-20=70
BC = sqrt(AB^2-AC^2) = sqrt(8.51^2-8^2) =~2.90
