Answer:
A system of linear equations usually has a single solution, but sometimes it can have no ... A system of linear equations has one solution when the graphs intersect at a point. ... one. If you find a root and your discriminant is <0 (which means the quadratic really ... P.S. you can't use the discriminant to check linear equations.
Step-by-step explanation:
6 itself is a multiple of 3, so any multiple of 6 is also a multiple of 3. We can
ignore the 3, and just find a number that's a common multiple of 4 and 6.
The way I do that is to investigate the multiples of 6, and just keep going until
I find one that's also a multiple of 4.
-- First multiple of 6 . . . 6. No, that's not a multiple of 4.
-- Second multiple of 6 . . . 12. Yes ! That's a multiple of 4.
So the least common multiple of 3,4,and 6 is 12.
After that, of course, multiples of 12 are also multiples of 3, 4, and 6, as well as
multiples of other numbers.
The 6 smallest multiples of 3,4, and 6 are ...
12, 24, 36, 48, 60, and 72 .
Answer:
6

Step-by-step explanation: To find the surface area for a pyramid, we can use this formula: ![A=lw+l\sqrt{(\frac{w}{2})^2 } +h^2+w\sqrt{(\frac{l}{y} } )^2+h^2](https://tex.z-dn.net/?f=A%3Dlw%2Bl%5Csqrt%7B%28%5Cfrac%7Bw%7D%7B2%7D%29%5E2%20%7D%20%2Bh%5E2%2Bw%5Csqrt%7B%28%5Cfrac%7Bl%7D%7By%7D%20%7D%20%29%5E2%2Bh%5E2)
Solution: ![10\times10+10\times\sqrt{(\frac{10}{2} } )^2+18^2+10\times\sqrt{(\frac{10}{2} } )^2+18^2=423.63](https://tex.z-dn.net/?f=10%5Ctimes10%2B10%5Ctimes%5Csqrt%7B%28%5Cfrac%7B10%7D%7B2%7D%20%7D%20%29%5E2%2B18%5E2%2B10%5Ctimes%5Csqrt%7B%28%5Cfrac%7B10%7D%7B2%7D%20%7D%20%29%5E2%2B18%5E2%3D423.63)
