"Twice the difference of three times a number and eight, divided by four" can be displayed as:
<u>2((8 - 3x)/4)</u>
Given problem:
.
Solution: We can see that first we have 8 and 2 numbers in front of 10's powers.
So, we need to simplify 8 over 2 first.
If we divide 8 by 2, we get 4.
Now, let us work on 10's and their powers.
is being divided by 
We can apply quotient rule of exponents remaining part.
According to quotient rule of exponents, 
If we apply same rule, we need to subtract exponents of 10's.

If we simplify exponent part -4-(-2), it will give us -4+2 =-2.
So, 
And final answer would be
.
Answer:
Step-by-step explanation:
Given data:
Circumference of the base of the cone = 24in.
Recall that circumference (in this case) is the distance round the base of the cone and from here the diameter D=12in. Radius = 6in
Surface area l = pie x radius ( slant height + radius)
= 3.142 x 6 (20 + 6)
= 3.142 x 6 (26)
= 3.142 x 156
= 490.152in^2
The answer is d because i just took a test and that was the answer
