Answer:
Step-by-step explanation:
Given:
To find
Solution:
In order to find we will subtract the function 
from 
So, we have:
Plugging in and in the above combinations of functions.
Simplifying by removing the parenthesis and reversing the signs of the terms in the parenthesis after the negative.
Combining like terms.
∴
6(3x+8)+32+12x
6•3x+6•8+32+12x
18x+48+32+12x
30x+48+32
30x/80
0.375
Answer:
4/9*pi or 1.395
Step-by-step explanation:
We have that area of the circle, that 4 * pi, we can calculate the radius of the circle, knowing that:
A = pi * r ^ 2
replacing:
4 * pi = pi * r ^ 2
r ^ 2 = 4 * pi / pi
r ^ 2 = 4
r = 2
Therefore, knowing the radius, we can calculate the perimeter:
P = 2 * pi * r
replacing:
P = 4 * pi
That is the perimeter of the whole circle, that is to say 360 °, therefore for 40 ° it would be:
4 * pi * 40 ° / 360 ° = 4/9 * pi
That is to say that the perimeter of the sector of 40 ° is 4/9 * pi, if pi is 3.14 it would be:
4/9 * 3.14 = 1.395
Hello!
2X + 4 = 14
X = 5
2 * 5 = 10
10 + 4 = 14
I hope this helps, and have a nice day!
