16. q-8=14
add 8 on both sides
q=22
Juanita did make an error, she should have combined -4 and -5 to make -9
Sometimes because it might not always be true
The Length of the play ground is 15 meter. The width is 5 meters. 15x5=75 and since 15 is 3x larger than 5 they should be the numbers we are looking for here.
So 15+15+5+5= 40 the perimeter of the playground should be 40 meters.
I hope this helps!
