Step-by-step explanation:
multiply the fractions numerator x numerator and then denominator x denominator and then simplify
<h3>I'll teach you how to solve (1/5x-4+2y)+(2/5x+5-4y)</h3>
-----------------------------------------------------------------
(1/5x-4+2y)+(2/5x+5-4y)
Remove parentheses:
1/5x-4+2y + 2/5x+5-4y
Group like terms:
1/5x+2/5x+2y-4y-4+5
Add similar elements:
3/5x+2y-4y-4+5
Add similar elements:
3/5x-2y-4+5
Multiply:
3x/5-2y-4+5
Add subtract the numbers:
3x/5+1-2y
Your Answer Is 3x/5+1-2y

Answer:
perimeter is 4 sqrt(29) + 4pi cm
area is 40 + 8pi cm^2
Step-by-step explanation:
We have a semicircle and a triangle
First the semicircle with diameter 8
A = 1/2 pi r^2 for a semicircle
r = d/2 = 8/2 =4
A = 1/2 pi ( 4)^2
=1/2 pi *16
= 8pi
Now the triangle with base 8 and height 10
A = 1/2 bh
=1/2 8*10
= 40
Add the areas together
A = 40 + 8pi cm^2
Now the perimeter
We have 1/2 of the circumference
1/2 C =1/2 pi *d
= 1/2 pi 8
= 4pi
Now we need to find the length of the hypotenuse of the right triangles
using the pythagorean theorem
a^2+b^2 = c^2
The base is 4 ( 1/2 of the diameter) and the height is 10
4^2 + 10 ^2 = c^2
16 + 100 = c^2
116 = c^2
sqrt(116) = c
2 sqrt(29) = c
Each hypotenuse is the same so we have
hypotenuse + hypotenuse + 1/2 circumference
2 sqrt(29) + 2 sqrt(29) + 4 pi
4 sqrt(29) + 4pi cm
By applying the segment addition postulate, the <u>value of v = 7</u>
- According to the Segment Addition Postulate, it holds that if point C is between points D and E, therefore:
DC + CE = DE

- Therefore, by substitution, we will have the following equation:

- Open the bracket and solve for the value of v.



v = 10
Therefore, using the segment addition postulate, the <u>value of v = 10</u>
