Describe how to find the least common multiple of three number .

Answers

Take the three numbers, and list all of their prime factors. I'll use 3, 9, and 21 for an example to help.
3: 3
9: 3 x 3
21: 7 x 3
You take the times that a number occurs the most in any of the three numbers and multiply them together. 3 occurs the most in a single number twice, and 7 occurs the most in a number once.
So you'd multiply 3 x 3 x 7 to get 63.

The width of a high school soccer field is 45 yards shorter than its length

Answers

a) W=L-45
b) a=L*W
Use the equation we created in part a and plug it into the area formula.
a=L*(L-45) 
9000=L(L-45)
9000=2L-45L
9000=-43L
L= -9000/43 
Now to find the width, plug in the length back into the first equation, in part a.
W=(-9000/43)-45
W= -10935/43 (Sorry if you need it in decimal form. Just plug it into a calculator :D)

How many sides and right angle and parallel sides a triangle had

Answers


-- Every triangle has three (3) sides and three angles. 
If it doesn't, then it's not a triangle.

-- A triangle can have one right angle, and no more than one.  But it
doesn't need to have one, and triangles don't always have one.

-- A triangle never has any parallel sides.
