Answer:

5x^2 + 20x = 5x(x + 4)

Step-by-step explanation:

Here, we want to factorize;

5x^2 + 20x

To do this, we start by writing the common factors

The common actor that we can see which is in the form of the gcf of both is 5x

Thus, the factorization will be;

5x^2 + 20x = 5x( x + 4)

The future value of $1,000 invested at 8% compounded semiannually for five years is $\bold{\$ 1,480}$

Solution:

$\bold{A = P (1 + i )^{n}}$ ----------- equation 1

A = future value

P= principal amount

i = interest rate

n = number of times money is compounded

P = 1000

i = 8 %

$\mathrm{n} = \text { compounding period } \times \text {number of years}$

(Compounding period for semi annually = 2)

$\mathrm{n} = \text { compounding period } \times \text {number of years}$

Dividing “i” by compounding period

$i = \frac{8 \%}{2} = 0.04$

Solving for future value using equation 1

$\begin{array}{l}{A = 1000(1 + 0.04)^{10}} \\\\ {=1000 (1.04)^{10}}\end{array}$

$= 1480.2$

$\approx 1,480 \$$
