Answer 1

what question?

Answer 2

Out of my depth sweetie, ask zzr0ck3r, he's good at math. :)

Answer 3

:)

Answer 4

the diagonals of a square are congruent...

Thus
\[\left( 2x-1 \right)+\left( 3y+5 \right)=4x-y+1\]

Answer 5

ok but how how do i solve it

Answer 6

i get the equation but dont know how to find the variables

Answer 7

@pgpilot326

Answer 8

so
2x + 3y +4 = x - y + 1

so

x + 4y = -3

Answer 9

but you also have the the fact that the diagonals of a square bisect each other...

so 2x-1 = 3y + 5 => 2x - 3y = 6

now you have a system of linear equations. Do you know how to solve these?

x + 4y = -3
2x - 3y = 6

Answer 10

no i dont to be honest can you help

Answer 11

yep... we can solve this by elimination
-2x + 4y = -3
2x - 3y = 6

and add...

y = 3

and plug it in...

2x - 3(3) = 6 => 2x - 9 = 6 => 2x = 15 => x = 15/2

so let's check in the original equations...

2x-1 => 2(15/2) - 1 = 15 - 1 = 14

3y + 5 = 3(3) + 5 = 9 + 5 = 14

and finally

4x - y + 1 = 4(15/2) -(3) + 1 = 30 - 3 + 1 = 28

so it all works out...

Whew!

Answer 12

wow man ur like extremelt good in math

Answer 13

hey, sorry I forgot a 4 ... it should have been 2x + 3y + 4 = 4x - y + 1

I forgot the 4 in front of the x on the right hand side.

my apologies. but I put it back in the above equations to solve. and I checked the solutions so were good.

Answer 14

i've been at it a little while... hehe

Answer 15

its ok man thank you

Answer 16

i voted u as best response

Answer 17

did you post your new question?

Thanks! and you're welcome!

Answer 18

i have 2 other questions but they dont need work out can u help\

Answer 19

yeah, just post them.

Answer 20

this \

Answer 21

what do you know about a rhombus?

Answer 22

diagonals are perpendicular and all sides are congruent thats all i know

Answer 23

diagonals are perpendicular bisectors of each other and yes, all sides are congruent.

but there's something a little more obvious than that... can you tell me what it is?

Answer 24

right angless

Answer 25

opp. angles are cong

Answer 26

not right angles (except in a square) and yes opp angles are congruent. something much more obvious... how many sides?

Answer 27

4 sides

Answer 28

yes... and what the interior angle sum of a quadrilateral?

Answer 29

not quiet sure sir.

Answer 30

better yet, what's the interior angle sum of a triangle?

Answer 31

all angles are equal to 180

Answer 32

the angles sum to 180. so 26 +m<1 +m<2 = 180 and 26 = m<1, right?

so m<2 = 180 - 2*26 = 180 - 52 =...

Answer 33

in the first one. I've got to get going now, sorry.

you have all the ammo you need to conquer this. best of luck!!!

Answer 34

ok thank u mannn ur the bestt

Answer 35
