Perimeter of this triangle=s+(s+4)+3s=5s+4
An expression that represents the perimeter of this triangle is: 5s+4
Answer:

Step-by-step explanation:
Hello There!
Once again we need to isolate the variable using inverse operations
to get rid of the -8.2 we add 8.2 to each side
-8.2+8.2 cancels out
-9.7+8.2=-1.5
now we have
-1.2z>-1.5
now we wan to get rid of the -1.2
to do so we want to divide each side by -1.2

Remember we have to flip the inequality sign because we're dividing by a negative number
we're left with
z<1.25
Answer:
not all of them are proportional because they do not all equal the same.
Step-by-step explanation:
To make a fraction to its simplest form, you have to divide the numerator and the denominator by the same number. For this question, divide 140 and 216 by 4. You will get 35/54. Since you can't divide this further, the simplest form of 140/216 is 35/54.
<em>Hope it helps</em> :)
