What is the smallest 3-digit number that has 2, 3, and 7 among its prime factors?

1 answer:

7 0

Answer: 126

Step-by-step explanation: You would just find the LCM (2, 3, 7) and get 42. But since you need a 3-digit number, list the multiples of 42, like so: 42, 84, 126, 168, 210...

As you can see, 126<em> </em>is the smallest 3-digit number that has 2, 3, and 7 among its prime factors.

4 - The area of a rectangle is 256.5m. If the length is 18m what is the perimeter of the rectangle? -

attashe74 [19]

The equation of the area of a triangle is Area=Length×Width. We know area=256.5 and length is 18. So now we know 256.5=18×width. We then divide 256.5÷18 to get the width. The width is 14.25. Perimeter=legth+length+width+width. If width is 18 and length is 14.25 then we add up all 4 sides. 18+18+14.25+14.25=64.5. 64.5 is the perimeter
