Answer:
Roughly 376.99 cm(If im doing this right.
Step-by-step explanation:
A = length x width
15,000 = (w + 30) x w
15,000 =

+ 30w
0 =

+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5

. Because distance cannot be negative, the width is -15 + 5

meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
90/2 = 45 degrees twices
These both are 45 degrees which is less than 90
Since those are the zeros, we can say that the equation would have to be
x(x-1)(x-6), then we just expand to get x^3 - 7x^2 + 6x
40% of the number 50 is 20
