Answer: The first five multiples of 21 are 21, 42, 63, 84 and 105.
Step-by-step explanation: The multiples of a number are all the numbers that are products of the number and any other integer. For example, the multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, and so on. Multiples are found by multiplying the number and any integer.
Answer:
287.7 u gotta be kidding,
Step-by-step explanation:
42×6.85=287.7
Answer:
When simplified this equation equals 8.
Step-by-step explanation:
Let me show you my work.
4 ( 3.5 - 1.5 ) = 4 ( 2 )
4 ( 2 ) = 8 because 4 times 2 = 8

Step-by-step explanation:
Let a = 8 and b = 11. Using the law of cosines, we can write
![c^2 = a^2 + b^2 - 2ab\cos{c}](https://tex.z-dn.net/?f=c%5E2%20%3D%20a%5E2%20%2B%20b%5E2%20-%202ab%5Ccos%7Bc%7D)
![\:\:\:\:=(8)^2 + (11)^2 - 2(8)(11)\cos{37} = 44.44](https://tex.z-dn.net/?f=%5C%3A%5C%3A%5C%3A%5C%3A%3D%288%29%5E2%20%2B%20%2811%29%5E2%20-%202%288%29%2811%29%5Ccos%7B37%7D%20%3D%2044.44)
![c = 6.67](https://tex.z-dn.net/?f=c%20%3D%206.67)
Now we're going to use the sine to find ![\angle{B}:](https://tex.z-dn.net/?f=%5Cangle%7BB%7D%3A)
![\dfrac{\sin{B}}{b} = \dfrac{\sin{37}}{c}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csin%7BB%7D%7D%7Bb%7D%20%3D%20%5Cdfrac%7B%5Csin%7B37%7D%7D%7Bc%7D)
or
![\sin{B} =\left(\dfrac{b}{c}\right)\sin{37} = 0.992](https://tex.z-dn.net/?f=%5Csin%7BB%7D%20%3D%5Cleft%28%5Cdfrac%7Bb%7D%7Bc%7D%5Cright%29%5Csin%7B37%7D%20%3D%200.992)
or
![B = \sin^{-1}(0.992) = 83.0°](https://tex.z-dn.net/?f=B%20%3D%20%5Csin%5E%7B-1%7D%280.992%29%20%3D%2083.0%C2%B0)
