-2 times -1 = positive 2
(two negatives cancel out to form a positive)
Answer:
The answer is C) -2 and 6
Step-by-step explanation:
x+4 / -3x^2 + 12x + 36
= x + 4 / -3 ( x^2 - 4x - 12)
= x - 4 / -3(x - 6)(x + 2)
the excluded values make the denominator = 0
so the answer is -2and 6
Answer:
Let's call the length of the field "l", and the width of the field "w".
If the area of the field is 72 square meters, then we have:
l x w = 72
And if the length is 6 meters longer than the width, we have:
l = w+6
So looking at the first equation (l x w = 72), we can substitute the l for a w+6.
And we obtain:
(w+6) x (w) = 72
Which simplifies to w^2 + 6w = 72.
This quadratic equation is pretty easy to solve, you just need to factor it.
w^2 + 6w - 72 = 0
(w-6)(w+12)
This leaves the roots of the quadratic equation to be 6 and -12, but in this case, a width of -12 wouldn't make sense.
So, the width of the rectangular field is 6, and the length of the field is 12.

Answer:
y= -5(x-4)
Step-by-step explanation:
any point slope equation is in form y-y1 = m(x-x1)
plug in the point and constant value
y-0 = -5(x-4)
y= -5(x-4)
