Answer:
height is 15
Y = L = Length
therefore 15y = (-x^2) +(300/20)
Step-by-step explanation:
15 = -x^2 +(300/20)
is the same as;
15 = (300/20) - (x^2)
we just add y to 15 and that can represent a division for x
y = L
Where area cm^2 can be shown as 300 as 15 x 20 = 300
when we divide by length we get the height as asked in the question.
Answer:
t=nm+r
Step-by-step explanation:
Since you are trying to find time, represented by t, you set the equation equal to t. Then you need to add n multiplied by miles, m, to the fixed rate, r.
