The numbers 7 and 14, 28 and 7 have the greatest common factor. The correct options are A and B.
<h3>What is the greatest common factor?</h3>
The largest factor of the two numbers which divides both the numbers is called as greatest common factor or GCF. In other words, the greatest common factor is the largest positive number which can be divided into given numbers evenly.
Given the number is 7 the pair of numbers having the greatest common factor is calculated below:-
For pairs 7 and 14. Both the numbers are the multiple of 7 it can be divided by 7. The greatest common factor will be 7 for pairs 7 and 14.
Similarly for pairs 7 and 28. Both the numbers are the multiple of 7 it can be divided by 7. The greatest common factor will be 7 for pairs 7 and 28.
Therefore, the numbers 7 and 14, 28 and 7 have the greatest common factor. The correct options are A and B.

Answer:
Step-by-step explanation:
<u>Increase of production:</u>
<u>Percent increase:</u>
First, we are going to multiply the pieces of wood by the length of each piece to find the total length she will need:
Next, we are going to convert 2262 centimeters to meters. To do that we are going to take advantage of the fact that 1 m=100cm:
Now, we just need to divide the total length of wood Marguerite needs by the length of each board of wood:
Since she will need full boards of wood, we must round 3.77 to its nearest integer 4.
We can conclude that <span>
Marguerite will need 4 boards of wood.</span>
Answer:
width = 7 and length = 9
Step-by-step explanation:
Let's assume width = w, and length = 2 + w
So area of a rectangle = width * length
63 ft² = w (2 + w)
63 = 2w + w²
w² + 2w - 63 = 0
Use the quadratic formula to solve this
here, a = 1, b = 2 and c = -63
w = 7 or -9
The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.
Width = 7 and Length = 7+2 = 9
