w = 4
L = 7
Step-by-step explanation:
L = length of rectangle
w = width of rectangle
L = 3 + w
A = 28
A = L*w
=(3+w) * w
28 = 3w + w^2
w^2 + 3w - 28 = 0
w^2 + 7w - 4w - 28 = 0
w ( w + 7 ) - 4 ( w + 7 ) =0
( w - 4 ) ( w + 7 ) = 0
w = 4. and w = -7
take the postive value, w = 4
therefore L= 3+4 = 7
Answer:

Answer:
The correct answer is 2
Step-by-step explanation:
The <em>correct answers</em> are:
It would take 5 months and she would save $250.
Explanation:
Let m be the number of months.
For the first way of saving, $200 up front and $10 each month, the expression would be
200+10m.
For the second way of saving, $100 up front and $30 each month, the expression would be
100+30m.
Setting them equal gives us the equation
200+10m = 100+30m
Subtract 10m from each side:
200+10m-10m = 100+30m-10m
200 = 100+20m
Subtract 100 from each side:
200-100 = 100+20m-100
100 = 20m
Divide both sides by 20:
100/20 = 20m/20
5 = m
It would take 5 months.
$200 up front and $10 each month for 5 months:
200+10m
200+10(5)
200+50
250
She would save $250.
