Distributive Property: a ( b + c) = (a*b) + (a*c)

b) x(x + 9) = x*x + 9*x

= x² + 9x

c) x² - 18x

x² = x * x

18x = 18 *x

G C F = x

Greatest common factor in both the terms is 'x'.Take the common variable from both the terms.

x² - 18x = x*x - 18*x

= x (x - 18)

Standard form. Factored form

x² x*x

x² + 9x x(x +9)

x² - 18x x(x - 18)

-x² + 10x x(-x + 10) = x(10 -x)

-x² - 2.75x -x(x + 2.75)

find the present value of an investment that is worth $19,513.75 after earning 3percent simple interest for 5.5 years

Dahasolnce [82]

Answer:

present value = $16750

Step-by-step explanation:

The simple interest formula allows us to calculate A, which is the final amount. According to this formula, the amount is given by A = P (1 + r*t), where P is the principal, r is the annual interest rate in decimal form, and t is the loan period expressed in years

simple interest formula:

t: time

P: present value

A: amount

r : anual interest

A = P (1 + r*t)

P = A / (1 + r*t)

P = 19,513.75 / (1 + 3/100 * 5.5)

P = 19,513.75/ (1 + 0.165)

P = 19,513.75 / 1.165

P = 16750

present value = $16750

Find the LCM of this set of numbers. 5 and 25

Andrej [43]

Answer:

Step-by-step explanation:

LCM = Least Common Multiple

To find the LCM, start by listing multiples, or the product of any two numbers.

5: 5, 10, 15, 20, 25, 30, 35...

25: 25, 50, 75, 100, 125, 150, 175...

Now, let's find the LCM by selecting the smallest shared multiple out of the lists we made.

5: 5, 10, 15, 20, 25, 30, 35...

25: 25, 50, 75, 100, 125, 150, 175...

Therefore, 25 is the LCM of 5 and 25.
