What is the greatest common factor of 45 and 72 please explain !!!!

Answers

Answer 1

Answer: The greatest common factor (GCF) of 45 and 72 is: 9

Factors of 45: 1, 3, 5, 9, 15, 45
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36

The common factors between the two numbers are 1, 3, and 9, but since 9 is the highest, it is considered the greatest common factor.

Answer 2

Answer:

The greatest common factor of 45 and 72 is 9.

The given numbers are

45 and 72

We know that,

The greatest common factor (GCF) is the biggest number that is a factor of two or more numbers.

The greatest number (factor) divides them, yielding a Natural number. Once all of the number's variables have been identified, there are a handful that are shared by both.

The greatest common factor is the largest number found among the common factors. The GCF is often referred to as the HCF (Highest Common Factor).

Now factorize 45

45 = 3x3x5

Now factorize 72

72 = 2x2x2x3x3

Now the common factors are:

3x3

= 9

Thus the GCF ⇒ 9

Mr. Hawkins is covering a room in carpet. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot of carpet costs $2.90. What is the cost of carpeting the room?

Answers

Answer:

The total cost of adding wallpaper to the room is $487.20

Step-by-step explanation:

Basically, how I got the answer is:

1. The shorter sides of the rectangle are 12 and the longer sides are 14.

2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.

3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.

Hope this helps! :)

first lets find the area of the floor.

A=l*w where l=length and w=width
Plug in the data
A=14*12
A=168ft²

If 1 square foot of carpet is 2.90$, then 168 square feet are...

1 sqft 168sqft
_______ = ________
2.90$ x$

Cross multiply
1x=487.20
divide both sides by 1
x=487.20 dollars

Answer= $487.20

is there a picture we can use to understand this?

Answer:

Answers will vary. For example, plugging in the test point (0, 0):

x + y ≤ 900

0 + 0 ≤ 900

0 ≤ 900

The test point (0, 0) holds true for the inequality.

surface area is like how much wrappin paper to wrap a present

anything to do with how much it can carry o it's volume aka capacity is not surface area

A is wrong, that's distance
B is correct
C, oval is not surface area, only distance
D is volume, how much concree

answe ri B

I believe its B.
because it can't be A. because its talking about volume
it cant be C. because that's perimeter
and it can't be D. because that is also volume.

What’s the answer for 6x+7-4x=8+7x-26

Answers

Answer:

x=7

Step-by-step explanation:

Add common variables.

(6x-4x)+7= 8+7x-26

2x+7= 8+7x-26

Subtract the least variable to both sides.

2x+7= 8+7x-26

-2x -2x

Now, simplify the equation.

7= (8-26)+5x

7= -18+5x

Add 18 to both sides.

7= -18+5x

+18 +18

Divide both sides by 5 to isolate the variable.

35= 5x

5 5

x=7
