Lydia is trying to prove that a quadrilateral in a coordinate plane is a square. First, she uses the slope formula to prove that

there are two pairs of parallel sides. Next, she uses the distance formula to prove that all sides are equal. What additional step must Lydia perform before reaching a conclusion that the quadrilateral is a square?

To be classified as a square, a quadrilateral must have 2 pairs of parallel sides, 4 sides equal in length, and 4 right angles. By using the slope formula, it can be determined whether the quadrilateral's sides are perpendicular<span>. If so, 4 right angles exist and the shape is a square. If not, the shape is not a square.</span>

Answer: Use the slope formula to prove that four right angles exist as a result of perpendicular sides.

Step-by-step explanation:

To be classified as a square, a quadrilateral must have 2 pairs of parallel sides, 4 sides equal in length, and 4 right angles. By using the slope formula, it can be determined whether the quadrilateral's sides are perpendicular. If so, 4 right angles exist and the shape is a square. If not, the shape is not a square.

Mr.Kent interviewed 54 students as they left the school. Is this a random sample? Explain. I will give Brainliest and please ans
malfutka [58]

Answer:

Hello there! :) This is not a random sample becuase the 54 students are'nt chosen at random.

Step-by-step explanation:

These students are pre-chosen by Mr. Kent, meaning that he could have biased whatever he was interviewing them on. And it does not mention anything like, the first 54 students to leave or the last 54 students to leave. I hope this helps!

Someone please help me on this question ?:)
katrin2010 [14]

Answer: The TV is 48 inches wide.

Step-by-step explanation: To find the solution to this equation we must use the Pythagorean theorem. The Py. Theo. is basically the formula :

a^2 + b^2 = c^2    You say this as "A squared plus b squared equals c squared"

To use this formula you must plug in the given values of a and b, to find c. A and b represent the two bases of the triangle, while c is the hypotenuse. In this equation we already have the value of c and a. We need to find b, but in order to do that we use a different formula. We use : c^2 - a^2 = b^2

See :

52^2 - 20^2 = b^2       *The ^2 means "to the power of" aka an exponent*

2704 - 400 = b^2     *When dealing with ^2, all you do is multiply the number by itself*

2304 = b^2      *Next, we find the square root of our current number.*

48 = b    

*Another way to solve this equation is to memorize all the Pythagorean Triples. With that knowledge, you wont even need to use the formula because you will already know all three values. I hope this helped you understand :)
