the width of a rectangle is 12 cm less than the length. the perimeter is 156 cm. find the width and the length.

Question

anonymous · Answer

this is basically the same as the other two problems you posted.  can you think of what the linear equations might be?

anonymous · Answer

no

anonymous · Answer

OK how would you say "the width of a rectangle is 12 cm less than the length", if width is W and length is L?

anonymous · Answer

ktlown help her btw L = 45 & W = 33

anonymous · Answer

how do u find it sheg

anonymous · Answer

kt will help u

anonymous · Answer

no wont i dont undertand his way

anonymous · Answer

OK if A is 12 less than B, can you write an equation that says that?

anonymous · Answer

nooo

anonymous · Answer

OK let's start easier.  If A is one more than B, can you write an equation that says that?

anonymous · Answer

no oh my gosh can u just write the equation so i can at least try to solve it

anonymous · Answer

I don't see the point of just giving you the answer without you understanding it.  If A is one more than B, then you could write A = B+1.  Does that make sense?

anonymous · Answer

see lil nick we have 
Let us suppose length is L

anonymous · Answer

yeah

anonymous · Answer

If the length is L can you write an expression for "12 less than the length"?

and it is given that width is 12 units less than length

anonymous · Answer

yeah

anonymous · Answer

If the length is L, can you write an equation for "12 less than L"?
