Question

MEDAL AND FAN!!!!!!
The perimeter of a rectangle is 50 cm and the length is 4 cm longer than the width. Write and solve the system of equations using the substitution method.
A. width = 10 cm, length= 14 cm
B. width = 10 1/2 cm, length= 14 1/2 cm
C. width = 11 cm, length= 15 cm
D. width = 23 cm, length= 27 cm

Answer 1

ermmmm

Answer 2

:0

Answer 3

ummmm okay

Answer 4

2L + 2W = P
is the formula for perimeter of a rectangle, yes or no?

Answer 5

yes

Answer 6

There are four sides, so to find the perimeter we just add them all up
perimeter=length+length+width+width

Answer 7

50=2×(width+4)+2×width

Answer 8

By substituting length with width + 4 we reduced the equation to a single variabale which we can solve.

Answer 9

so A?

Answer 10

Mhmm~

Answer 11

I think it is asking for the solution to be specifically substitution by system of equation

Answer 12

.....ihave no clue what you said:(

Answer 13

nvm

Answer 14

here's what is being sought for: Write and solve the system of equations using the substitution method.

Answer 15

yeash iknow i just dont know how to

Answer 16

that is the purpose of this drill - for you to learn how to do it

Answer 17

yep

Answer 18

2L + 2W = P
-------------
2L + 2W = 50
L = W+4
your composition should start out like this
