L=w+3
P=2l + 2w
2l= 2w+6
130=4w+6
-6 -6
124 = 4w
31= w
width= 31 length = 34
The answer is 21.5 or in a fraction its 43/2
Perimeter of triangle is adding all three sides.
For example a triangle with sides 3, 5, and 7 would have a perimeter of 15
Now we use your values.
632 = (x) + (3x) + (3x + 2)
632 = 7X + 2
630 = 7x
90 = X
So side 1 is 90
Side 2 is 3(90) or 270
Side 3 is 3(90) + 2 or 272
Add all those up and you get (you guessed it) 632
Answer: 11:7
Step-by-step explanation:
Number of green colored pencils=11
Number of blue colored pencils= 7
Number of red colored pencils= 3
Total number of colored pencils= 11+7+3= 21
Ratio of green colored pencils to blue colored pencils= 11:7
The mean will go up, however little
The standard deviation will also go up.
hope this helps
