I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Answer:
it is a simultaneous equation and I used Elimination method
<span>The perimeter of the area is the length of the fence.
Perimeter = x + y + y. This can be simplified to
Perimeter = x + 2y. You're told that the rancher has 100 m of fence, so the perimeter is 100 m:
100 = x + 2y (1)
The area of a rectangle is given by the formula A = length * width. The length in this case is x, and the width is y.
So, A = xy.
Solve equation (1) for y. Once you find the expression to which y equals, plug that for y into A = xy.
100 = x + 2y. Solve for y by subtracting both sides by x:
100 - x = 2y. Divide both sides by 2:
(100 - x)/2 = y
Substitute (100 - x)/2 for y into A = xy:
A = x[(100 - x)/2]
A = [x(100 - x)]/2
You can rewrite this as (100x - x²)/2 or 50x - (x²/2) or 50x - (1/2x²).
Hope that helped!</span>
Answer:
3,50$
Step-by-step explanation:
(2,25 x 4) + 7,50 = 16,50$
