LMNP is a rectangle. Find the value of x and the length of each diagonal.
LN = 5x + 19 and MP = 8x - 8
x=0

Answers

Question:

LMNP is a rectangle. Find the value of x and the length of each diagonal.

LN = 3x + 1 and MP = 8x – 4

Answer:

Value of x = 9, Length of LN = 64, Length of MP = 64

Solution:

Given LMNP is a rectangle. LN and MP are diagonals.

LN = 5x + 19 and MP = 8x – 8

Diagonals of a rectangle are equal in length.

⇒ LN = MP

⇒ 5x + 19 = 8x – 8

Combine like terms together.

⇒ 19 + 8 = 8x – 5x

⇒ 27 = 3x

Divide by 3 on both sides of the expression, we get

⇒ x = 9

The value of x is 9.

To find the length of the diagonals.

LN = 5(9) + 19

= 45 + 19

LN = 64

MP = 8(9) – 8

= 72 – 8

MP = 64

Length of LN = 64 and the length of MP = 64.

What is -7/9 x 3/5
PLEASE HELP

Answers

Your answer would be -7/15

-7/15
Reduce the 9 to 3 and the 3 to 1. Next, multiply straight across. Negative times positive = negative. Therefore, -7/9 x 3/5 = -7/15

Why is it difficult/ impossible to find even prime numbers?

Answers

It is difficult because prime numbers are numbers with no factors. There's not many. A lot of one digit numbers are prime and odd numbers but after 2, all of the even whole numbers are composite and some odds past 100 (and some before 100) are, also

What's the REAL square root of pi?

Answers

Every positive number has two square roots. Since pi itself is irrational, you can be sure that its square roots are also irrational, so they can't be written exactly using digits. They're roughly +1.77245... and -1.77245... (both rounded).

A picture frame is 9 inches long and 6 inches wide. It can display a picture 6 inches long and 4 inches wide. What is the area of the picture frame?

Answers

Answer:

30 inches squared

Step-by-step explanation:

First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.

Answer:

30 in^2

Step-by-step explanation:

Frame

Length = 9

Width = 6

9 * 6 = 54in^2 (Multiply to get 54)

Picture

Length = 6

Width = 4

6*4 = 24in^2 ( Multiply to get 24 )

54 - 24 = 30in^2 ( Minus 24 from 54 to get 30)
