Answer:
O y = (x + 5) (x + 3)
Step-by-step explanation:
y = (x + 4)² - 1
y = x² + 8x + 15
y = x² + 3x + 5x + 15
y = x(x + 3) + 5(x + 3)
y = (x + 5) (x + 3)
Answer:
below
Step-by-step explanation:
add -36 to both sides
divide both sides by 2
This is a quadratic equation
let's solve it by graphing it
The solution are the x-coordinates of the intersection points
The x-coordinates of the intersection points are approximatively -1.6 and 5.6
Answer:c
Step-by-step explanation:
The instantaneous rate of change is simply equivalent to
the first derivative of the equation or function. We are given the equation of
Surface Area (A) with respect to side (x):
A = 6 x^2
Taking the first derivative of the equation:
dA = 12 x dx
dA / dx = 12 x
Now the term dA / dx is the instantaneous rate of change
in the surface area with respect to the side length. To get the rate of change
when the side x = a, simply plug this in into the equation:
rate of change = dA / dx = 12 x
so when x = a:
<span>rate of change = 12 a</span>
A cube root is representaive of reverse mutiplication. E.g Square root of 4 is 2 (2x2)
Using this, we can see that anytime 3 negatives are multiplied, the answer will always be negative.
