A) 3x+2
Step-by-step explanation:
Answer:
43.96
Step-by-step explanation:
I used the formula SA= 3.14(2)5+3.15(5^2)
#8. The answer would be 189. The LCM (least common multiple) of 2 or more numbers, is the multiple that each number has in common with one another. Here are the multiples of both numbers up to 189, to show 189 is the answer.
- 21: 21, 42, 63, 84, 105, 126, 147, 168, 189
- 27: 27, 54, 81, 108, 135, 162, 189
#9. The answer would be 41. Prime numbers are numbers that only have 2 favtors (1 and itself). Since 41 is only divisible by 1 and itself, without the answer being a decimal, it is a prime number.
#10. The answer would be 6. The GCF (greatest common factor) of 2 or more numbers, is the largest factor that each number has in common with one another. Here are the factors of both numbers, to show 6 is the answer.
- 30: 1, 2, 3, 5, 6, 10, 15, 30.
- 48: 1, 2, 3, 4, 6, 8, 12, 24, 48.
I hope this helps!
The normal to the plane required is the cross product of the direction vector of the line of intersection of the planes and the normal vector of the other plane.
