We know that the perimeter of a rectangle can be represented by the expression 2l +2w, where l represents the length of the rectangle and w represents the width of the rectangle.
If we substitute in the values given in this problem, we get the expression:
2(2x+6) + 2(x)
Another equivalent expression we can use to express the perimeter is w + w + l + l.
If we substitute in the values given in this problem into this expression, we get:
x + x + 2x + 6 + 2x + 6
Overall, we know that these expressions are equivalent and represent the same value (the perimeter of the rectangle), because if you combine like terms, both expressions simplify to 6x + 12.
Hope this helps!
Thank you for coming to Brainly with your questions!
I believe the answer is:
7:2. I found this by setting up the ratio 28:8. We have to simplify this ratio, and the greatest common factor (GCF) is 4, so divide both sides by 4, and you get 7:2.
I hope this helps you! Please mark Brainliest! Lemme know if I can help you with any further questions!

Answer:21
Step-by-step explanation: If the formula I've used was right. All you had to do was use the percentage of the children who liked science more which is 35% and change it into a decimal like 0.35 and multiply that with 60 and your answer is 21!
K = 1
the difference between the two variables is just 1
y=x+1
It would be 9, 9 1/2, 10, and 10 1/2. I think.
