Answer:

Lcm=18

Step-by-step explanation:

First do prime factorization of 6 and 9

common factor of 6 is 3

and remaining factor is 2×3

Now,

C.F×R.F= 3×2×3

If a triangle has side 6 feet and 9 feet and perimeter is 23 feet , how long is the third side ?

tiny-mole [99]

The perimeter of a triangle is found by adding all the three sides.

Let's call the third side "x"

So,

6+9+x = 23

15+x = 23

x = 8

Answer:

The length of the line segment is of 5.9 units.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, $(x_1,y_1)$ and $(x_2,y_2)$ . The distance between these two points is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

How long is the line segment?

The distance between points P and Q. So

P(1,3), and Q(4,8).

$D = \sqrt{(4-1)^2+(8-3)^2} = \sqrt{3^2 + 5^2} = \sqrt{34} = 5.9$

The length of the line segment is of 5.9 units.

Help me out please simple

const2013 [10]

A straight line is 180 degrees in measure

The straight line is made up of three angles

--> angle 1

--> angle 2

--> angle with a little square on it

(angle with a little square means it is 90 degrees in measure)

Let's set up an equation

$angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3$

Thus angle 1 is 3 degrees or the second choice

Hope that helps!

The perimeter of a rectangle is 32cm, its length is more than its width by 2 what's the area

White raven [17]

Answer:

63 cm^2

Step-by-step explanation:

p = l + w + l + w

32 = 2l + 2w

32 = 2(w + 2) + 2w

32 = 2w + 4 + 2w

32 = 4w + 4

28 = 4w

7 = w

l = w + 2

l = 7 + 2

l = 9

Check your work:

32 = 9 + 7 + 9 + 7

32 = 32

Correct

A = l × w

A = 9 × 7

A = 63
