Answer:
width =19 inches
length= 27 inches
Step-by-step explanation:
Let width be w inches so according to given scenario as length is 8 more than width so the equation becomes
l=8+w inches (Equation 1)
Area of Rectangle= L*w
Area= 513
L*w=513 (Equation 2)
Putting l's value from equation 1 in equation 2
(8+w)w=513
w^2+8w-513=0
Making Factors
w^2+27w-19w-513=0
w(w+27)-19(w+27)=0
(w-19)(w+27)=0
w=19, w=-27
as width cannot be negative so if we only consider w=19 then
l=8+19
l=27

Answer:
15 weeks
Step-by-step explanation:
Let the number of weeks = x.
At the end of x weeks,
Jeremy has 120 + 14x,
and Katie has 180 + 10x
We want to know when their amounts are equal.
120 + 14x = 180 + 10x
4x = 60
x = 15
Answer: 15 weeks
