Am I supposed to add an =0 to both perimeters? 6x+2=0 4x+8=0
ganeshie8
  • ganeshie8
perimeter of first pool = 2(2+x + 2x-1) = 2(3x+1) = 6x+2

perimeter of second pool = 2(x+2+x+2) = 2(2x+4) = 4x+8
ganeshie8
  • ganeshie8
read the q once, it says, perimeters are equal eh ?
ganeshie8
  • ganeshie8
so... lets set them equal 6x+2 = 4x+8
ganeshie8
  • ganeshie8
can u solve x ?
Mathhelp346
  • Mathhelp346
Oh oops x=3
ganeshie8
  • ganeshie8
yes, next find perimeter of pools also
Mathhelp346
  • Mathhelp346
Ok so they're both 20
ganeshie8
  • ganeshie8
Yes :)

Can you help me with #25?
ganeshie8
  • ganeshie8
try to form an equation
ganeshie8
  • ganeshie8
product of 3 and the sum of a number and 5 3(x+5)
ganeshie8
  • ganeshie8
then added to 6 3(x+5) + 6
ganeshie8
  • ganeshie8
is the same as 3(x+5) + 6 =
Mathhelp346
  • Mathhelp346
the same as the product of 2 3(x+5)+6=-2(x-3)-5 ?
Mathhelp346
  • Mathhelp346
Would that be correct?
ganeshie8
  • ganeshie8
careful about how it was worded, it says difference of the same number \(from\) 3
Mathhelp346
  • Mathhelp346
?
ganeshie8
  • ganeshie8
it doesnt say, difference of same number and 3 since, it says from 3, we must subtract x from 3
ganeshie8
  • ganeshie8
3(x+5)+6=-2(3-x)-5
Mathhelp346
  • Mathhelp346
ohh
Mathhelp346
  • Mathhelp346
So the answer would be x=-32?
ganeshie8
  • ganeshie8
yup !

  • Mathhelp346
Ok :)
