area=legngth tiimes width
legnth is 10 more than 2 times width
l=10+2w
lw=area=(10+2w)w=10w+2w^2
area=3600
3600=10w+2w^2
so divide by 2
1800=5w+w^2
subtract 1800 from both sides
(note they used x instead of w)
0=w^2+5w-1800
then the facotred form is (w-40)(w+45)=0
0 product property measn if you have xy, then x and or y =0
therefor
w-40=0 and w+45=0
w=40 or -45
discard negative because negative legnth is not possible
explian how solution relates to situation
it is math so it is correct because we represented it corrrectly
the other solution is because of math and eliminate negative legnth becasue tha tis not possible
basically because we represented it correctly
not a very clear quetion to answer
basically 'because it represents the solution so we solved it and it is correct'
The mean of those sets of numbers are 17.5

How is this going to help you get ur work done?
Step-by-step explanation:
Answer:
x = 6 y = 5
Step-by-step explanation:
-8x + 3y = -33
y = -5x +35
-8x + 3(-5x + 35) = -33
-8x - 15x + 105 = -33
-23x + 105 = -33
-23x = -138
x = 6
-8(6) + 3y = -33
-48 + 3y = -33
3y = 15
y = 5
Answer:
The percentage of discounted tickets with respect to total tickets is 75 %
Step-by-step explanation:
Given as :
The total tickets of amusement park = 5,000
The total discounted tickets of amusement park = 3,750
Let The percentage of discounted tickets with respect to total tickets = D %
Now, According to question
The discounted percentage =
× 100
or, D =
× 100
or, D = 0.75 × 100
or D =
× 100
∴ D = 75 %
So, percentage discounted tickets = D = 75 %
Hence The percentage of discounted tickets with respect to total tickets is 75 % . Answer
