D)
24x + 52

Answer 2

@heyyitspaige can you help on this one?

@563blackghost

Answer 5

can you help?

Answer 6

Yea I was just trying to understand what we gotta do ^^

Answer 7

lol k

Answer 8

OK since its a rectangle that means the oppisite of the known part of the rectangle is the same.... so

Answer 9

So the equation would be \[((2x+7)+(4x+5))\times2\]

Answer 10

This is for the first rectangle...

Answer 11

k

Answer 12

So we first combine like terms.... so we add 2x + 4x and 7 +5....so what is the simplified equation?

Answer 13

6x +11?

Answer 14

Close its 6x+12 ^^ Now we must multiply by 2 to it....\[(6x+12)\times2\] so we multiply 6x by 2 or 6x + 6x and we multiply 12 by 2 or 12 + 12....

Answer 15

whaaaaa im lost now?

Answer 16

oh wait i get it

Answer 17

ok good ^^

Answer 18

sorry my internet is bad right now...

Answer 19

So you figured it out?

Answer 20

@gigi1103

Answer 21

yas its b right?

Answer 22

Incorrect...we want to know the "combined" peremeters which is of the two triangles so we only know of one and we need to know the other one and then we will add those two up....

Answer 23

ohhhhhh

Answer 24

^^ to be honest I thought that too but i saw that it said "combined" and I had the exact response xD

Answer 25

lol

Answer 26

So do you still need help or you can do the other part?

Answer 27

can you help me on the last part?

Answer 28

Sure ^^ now we know of the perimeter of the first rectangle which is 12x +24 now we need to know the other one.... so like said we will add both of the equations and then multiply that by 2...\[((3x+14)+(3x))\times2\]

Answer 29

So we first combine like terms so 3x + 3x and 14 will left alone since it does not have any other terms like it.... \[?x+14\]

Answer 30

6x +14?

Answer 31

Correct ^^....now we need to multiply 6x+14 by 2....\[(6x+14)\times2\] so we multiply 6x by 2 or 6x+6x and we multiply 14 x 2 or 14+14...

Answer 32

so 12x and 28

Answer 33

Correct again ^^....so we now we know of the total perimeters of both rectangles so now we need to add both of these....\[(12x+24)+(12x+28)\] So we first combine like terms so 12x +12x and 24+28....

Answer 34

so 38 +40

Answer 35

Incorrect....try again ^^

Answer 36

24x qnd 52?

Answer 37

Correct! The equation of the combine rectangles is
\[24x+52\]
Great Job! ^^

Answer 38

thanks!!!

Answer 39
