the rates of change will be 210. if the change is after 8 hours than the rate of change will be 105
Answer:
The equation in standard form is:
x^2-40x-6000 = 0
Step-by-step explanation:
Let the length of the field be x yards.
Now the width of the field is 40 yards less than the length of the field.
Thus, the width of the field would be (x-40) yards
Now, to calculate the area of the field, we simply multiply the length of the field by the width of the field.
Hence;
Since the shape is rectangular, the area is the product of the length and that of the width
x(x-40) =6,000
x^2 -40x = 6,000
x^2-40x-6000 = 0
I’m pretty sure it’s the second one
All I did was add all A's, B's, and C's separately. Than I added them all together and got 316 total surface area. I tried but I learned this sooo long ago so i'm sorry if you get it wrong. Good Luck!
For this case we must factor the following expression:

We must find two numbers that, when multiplied, result in 9 and when added, result in -6.
These numbers are -3 and -3.

Then, the factored expression is of the form:

Thus, the correct option is option C.
ANswer:
Option C
