Answer:
2 11/12
Step-by-step explanation:
1 1/2+ 2/3+3/4
The common denominator is 12
1 1/2*6/6+ 2/3*4/4+3/4*3/3
1 6/12 + 8/12 + 9/12
Add together
1 +23/12
1+12/12 +11/12
1+1+11/12
2 11/12
You can use the equation

to find the lenth of the legs
x = leg 1
x + 14 = leg 2
Answer: She could create 60 platters.
Step-by-step explanation:
Given: A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose from.
Number of combinations of selecting <em>r</em> things from <em>n</em> things is given by:-

So, the number of combinations of selecting 2 different vegetables from 6 = 
Now, By Fundamental counting principle, the number of different platters she could create = (number of ways of selecting 2 different vegetables from 6) x (Number of sizes)
= 15 x 4
= 60
Hence, she could create 60 platters.
Rectangular with whole numbers
perimiter=legnth+legnth+width+width=2l+2w
therefor
p=2l+2w=2(l+w)
p/2=l+w
perimiter=20
20=2l+2w
divide by 2 to make simpler
10=l+w
find all combos
l>w so
l=9 and w=1
l=8 and w=2
l=7 and w=3
l=6 and w=4
combos
