The length, l, is 2 more than twice the width, w.
l= 2w+2 (2 more than twice w)
In a rectangle, we have two of the same lengths and two of the same widths.
2l+2w=34
Divide by 2 on each side.
l+w=17
We remember that l is 2w+2
Substituting that back in we get,
2w+2+w=17
3w+2=17
3w=15
w=5
We sub w back into l+w=17
l+5=17
l=12
The dimensions are 5 by 12 inches.
In the above question 13m=156 we are dividing both sides by 13 so that m=12 .As 
According to Division property of Equality: If you divide one side of an equation by a number, you also must divide the other side by the same number so that your equation stays the same.
The property Division Property of Equality is justified .
Answer:
1
Step-by-step explanation:
5^0
Any number other than 0 raised to the power of zero is 1
5^0 =1
Perimeter is the out side to think the outside of a rug and area in the inside so the outline of you room all you have to do is add the numbers given you can me only two numbers but let’s say you have a square that has 4 written on each side add 4 four times so 4+4+4+4=16 got it?
Answer:
129.9 cm^2
Step-by-step explanation:
You can use the Law of Sines to find the hypotenuse. Because it's an equilateral triangle, it's the same value for the base. If you plug in the proper angles, being 90 degrees and 60 degrees because it's an equilateral triangle, the value of the base should be 17.32050808, or 17.32 if we're rounding. If you use the usual formula for finding the area of a triangle, b * h / 2 to get an answer of 129.9 cm^2. Hope this helps and isn't too confusing! There's a bunch of lessons on Khan Academy if you need more help!
This is a bit advanced for middle school, so we might be missing some information.
