Answer:

$2x(x+3)$

Step-by-step explanation:

We'll start by doing simple things.

We see that there is a common factor of 2 so we will first take that out:

$2(x^2+3x)$

Now we see that we can also take out an $x$ :

$2x(x+3)$

Now we can't take out anything else. Done!

Answer:

2x(x+3)

Step-by-step explanation:

To factor, you need ti find what's the greatest common factor in your expression.

in this case, the expression is divisible by 2x, since both parts of the equation are divisible by 2x

when you take out 2x, you are left with x+3. there's nothing else to factor, so this is the simplest form:

2x (x + 3)

Y=−3(2.5)x

Hoochie [10]

Answer:

1. The equation represent an exponential decay

2. The rate of the exponential decay is -3×2.5ˣ·㏑(2.5)

Step-by-step explanation:

When a function a(t) = a₀(1 + r)ˣ has exponential growth, the logarithm of x grows with time such that;

log a(t) = log(a₀) + x·log(1 + r)

Hence in the equation -3 ≡ a₀, (1 + r) ≡ 2.5 and y ≡ a(t). Plugging in the values in the above equation for the condition of an exponential growth, we have;

log y = log(-3) + x·log(2.5)

Therefore, since log(-3) is complex, the equation does not represent an exponential growth hence the equation represents an exponential decay.

The rate of the exponential decay is given by the following equation;

$\frac{dy}{dx} =\frac{d(-3(2.5)^x)}{dx} = -\frac{d(3\cdot e^{x\cdot ln(2.5)})}{dx} = -3 \times 2.5^x\times ln(2.5)$

Hence the rate of exponential decay is -3×2.5ˣ × ㏑(2.5)

(f(1) = -16<br> | f(n) = f(n-1).<br> f(3) =

Sauron [17]

Answer:

f(3) = -16

Step-by-step explanation:

f(1) = -16

f(n) = f(n-1)

f(2) = f(2-1) = f(1) = -16

f(3) = f(3-1) = f(2) = -16
