Answer:
-(1/10)x
Step-by-step explanation:
This is an addition problem. Since the variable (x) is the same in both terms, we need only sum up the coefficients -3/5 and 1/2 and then multiply x by this sum.
-3/5x+1/2x = (-3/5 + 1/2)x
The LCD of -3/5 and 1/2 is 10. The -3/5 term converts to -6/10 and the 1/2 term to 5/10. Thus, we have (-6/10 + 5/10)x = -(1/10)x
Total surface area of cone: πrl + πr²
Assuming the bottom of the cone is closed.
r = r/2, l = 2l
Total surface Area = π*(r/2)*2l + π(r/2)² = πrl + πr²/4
Total Surface Area = πrl + πr²/4

Step-by-step explanation:
<h3>Answer;</h3>
-Coplanar lines
A transversal must intersect two or more <u>coplanar</u> lines.
<h3>Explanation;</h3>
- Coplanar lines are lines that lie on the same plane.
- Examples of such lines include perpendicular lines, parallel line and any two straight lines that have a common point, such as the three edges of a triangle.
- A transversal cuts two or more parallel lines, which are coplanar, that is they lie on the same plane
As it is right angled, thus it will be equal to 90.
= 2x + 5 + x + 25 = 90
= 3x + 30 = 90
= 3x = 60
= x = 60/3
= x = 20
