Since a square has 4 equal sides, just do 19 + 19 + 19 + 19 which is 76. Or, 19 x 4, even though you add with permieter, it'll still work on a square.

Answer:
Letters A. and D. would fill in the blank correctly.
First, we would set the number to x.
Then, we turn the words into an equation.
x+75 = 3x-39
Isolate the x.
-2x = -114
So...
x = 57
Answer: See below.
Step-by-step explanation:
Let's go number by number.
Rational pretty much means you can put it into a fraction of whole numbers.
The first number is -81,572.
- This number is <u>rational</u> because it can be put into a fraction (
) that is made up of whole numbers.
The second number is
.
- This number is <u>irrational</u> because it cannot be put into a fraction of whole numbers.
- Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.
The third number is 5.636336333
- There is a pattern so the number is <u>rational</u>.
- Usually a pattrn means it can be put into a fraction.
The fourth number is
. This equals 4 if you solve it out.
- Since we just get 4, that certainly can be put into a fraction of whole numbers, so this is <u>rational.</u>
The answer is 7 7/12
