The answer is <span>A. 16 edges
For most of the solid shapes, we can use Euler's polyhedron formula:
f + v - e = 2
f - the number of faces
v - the number of vertices
e - the number of edges
We know:
f = 5 + 4 = 9
v = 9
e = ?
So:
</span>f + v - e = 2
9 + 9 - e = 2
18 - e = 2
18 = e + 2
e = 18 - 2
e = 16
Answer: 180 = 30 + (x + 60)
Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.
Answer:
1. A number having 2, 3, 7 or 8 at unit's place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8. The number of zeros at the end of a perfect square is always even. In other words, a number ending in an odd number of zeros is never a perfect square.
2. Only those numbers, when squared will have 6 at their unit place are 4 and 6 Because 4×4 = 16 and 6×6 = 36(i dont know if this is what you were looking for)
3. the square root of 24336 consists of three digits and those digits are 156
Step-by-step explanation:
i am sorry my brain hurts lol, i will answer the 7 other questions later
Answer:
1. -3 = -8, 0 = 1, 2 = 7
Step-by-step explanation:
1. Plug in the x values for x in the equation and graph the coordinates (examples; (-3, -8))
2. do the same thing as #1
example; y = -(-3) - 2
3. Plug in 2 into the equation, giving you your y value, and plug the coordinates in
4. you can make up the x coordinates, I would do -1, 0, 1, and 2. and just plug those in for the x in the equation and graph.
5. Follow the same steps as the last problems but just connect the points
6. Same steps as the other problems, just pick some points and plug them into the equation.
I hope this helps
Answer:
Step-by-step explanation:
We can observe the numbers 72, 78, 84, 90 form an arithmetic sequence with common difference of 6.
<u>It can be continued by adding 6 to the last number:</u>
