The length of a rectangle is 4 more than twice the width. The perimeter is 74 feet. Find the length and width of the rectangle.
mafiozo [28]
(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26

Select each equation which is equivalent to 60% of 25.
Maksim231197 [3]

The equation which is equivalent to 60% of 25 is x = 0.6 * 25

An equation is used to show the relationship between variables, numbers.

Let x represent the value of 60% of 25. Hence:

x = 60% of 25

x = 0.6 * 25

Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25

x/25 = 60/100

6/10 = x/25

The perimeter of a rectangle is 28 cm and<br>its length is 8 cm. Find its breadth.​
Yakvenalex [24]
Answer:
The width of the rectangle is 6cm.

Explanation:
Perimeter=2(length+width)
28=2(8+w)
Distribute 2 into the parentheses
28=16+2w
Combine like terms
28-16=2w
12=2w
Divide both sides by 2
6=w

I hope this helps! Please comment if you have any questions.
