Question

In rectangle PQRS, PR = 18x – 25, and QS = x + 825. Find the value of x and the length of each diagonal.

Answer 1

x = 50; PR = 875; QS = 875
x = 51; PR = 893; QS = 893
x = 50; PR = 437.5; QS = 437.5
x = 25; PR = 850; QS = 850

Answer 2

These are big numbers.....

Answer 3

In any rectangle, the diagonals are congruent (or equal in length)

Answer 4

so this means

PR = QS

18x – 25 = x + 825

Answer 5

Please give me step by step instructions, Thank you :-)

Answer 6

all you need to do from here is solve

18x – 25 = x + 825

for x

Answer 7

do you know how to do that?

Answer 8

Okay! Got it

Answer 9

tell me what you get

Answer 10

X=5

Answer 11

right?

Answer 12

no

Answer 13

if possible, write out your steps so I can see where you went wrong

Answer 14

x+825 = 18x-25
x+825-825=18x-25-825
x=18x-850
-17x=-850
x=-850/-17
x=5

Answer 15

I get x=5 What am I doing wrong? My coices are: x = 50; PR = 875; QS = 875
x = 51; PR = 893; QS = 893
x = 50; PR = 437.5; QS = 437.5
x = 25; PR = 850; QS = 850

Answer 16

-850/-17 is NOT 5

Answer 17

I thought two negetives get you a positive number

Answer 18

you mistakenly did -85/-17 to get 5

but the real thing you should type in is -850/-17

Answer 19

I thought I did that x=-850/-17

Answer 20

try it again

Answer 21

I forgot to carry the fargin 0...haha the answer is x=50

Answer 22

yep, x = 50

Answer 23

once you know x = 50, use it to find PR and QS

Answer 24

lol....Thank you!
