To answer this question you can use the Pythagorean Theorem Which states that a squared plus b squared equals c squared. C is the hypotenuse of a triangle (one of the diagonals forming the X). The hypotenuse is the side directly across from the right angle. A and b are both 12, so 12 squared plus 12 squared is 288. To solve for c, find the square root of 288, which is approximately 17 inches. Double this (one for each line in the X and you need approximately 34 inches of ribbon. Always label your answers!

Consider the following expression and determine which statements are true.
Serhud [2]

Given:

$\frac{7}{r}+2^{3}+\frac{s}{3}+11

To find:

Which statement are true?

Solution:

Option A: The entire expression is a sum.

It is true because it performed addition operation.

Option B: The coefficient of s is 3.

$\frac{7}{r}+2^{3}+\frac{s}{3}+11=\frac{7}{r}+2^{3}+\frac{1}{3}s+11

It is not true because the coefficient of s is \frac{1}{3}.

Option C: The term \frac{7}{r} is a quotient.

If we divide 7 by r, we obtain a quotient.

So it is true.

Option D: The term 2^3 has a variable.

It is not true because it does not contain any variable.

Therefore the entire expression is a sum and the term \frac{7}{r} is a quotient are true statement.
