Divide both sides by -5
You would then get (square root)x=3 since the negatives would cancel out
Then you square both sides
You will be left with (x)*2=(3)*2
Your answer will be C. X=9
Hope that helped!
What seems to be the issue?
The perimeter is equal to 60 feet and has the formula:
Perimeter = 2 l + 2 w
60 = 2 l + 2 w
The area is equal to 200 square feet and has the formula:
Area = l w
200 = l w
Rewriting area in terms of l:
l = 200 / w
Combining this with the perimeter formula:
60 = 2 (200 / w) + 2 w
60 = 400 / w + 2 w
Multiplying all by w:
60 w = 400 + 2 w^2
Dividing by 2 and rearranging:
w^2 – 30 w = - 200
Completing the square:
(w – 15)^2 = - 200 + (-15)^2
(w – 15)^2 = 25
w – 15 = ±5
w = 10, 20
Hence the dimensions of the garden is 10 feet by 20 feet
I can't see the rest of the graphs.
Answer:
Step-by-step explanation:
Let x represent the number of cars that Jamie washes.
Let y represent the number of pies that Stella makes.
The amount of money needed by Jamie and Stella to sign up for the trip is $600 each
Jamie earns $25 for each car washed. This means that if he washes x cars, he would earn 25×x =$25x
Stella earns $15 for each pie made.
This means that if she makes y pies, she would earn 15×y =$15y
Part 1) The inequality is
25x greater than or equal to 600
Part 2)The inequality is
15y greater than or equal to 600
Part 3) Stella only has enough supplies to make 40 pies. Total amount made from 40 pies would be 40×15 = 600
Jamie's earnings is
25x greater than or equal to 600
Stella's earnings is
15y lesser than or equal to 600
Part 4) Maximum amount of money that Stella can earn is 15×40 = $600
Therefore, Stella can afford to sign up for the trip.
