Ethan finds some dimes and quarters in his change purse. How much money (in dollars) does he have if he has 12 dimes and 4 quart

Masja [62]

So a dime is .10 or 10 cents

a quarter is .25 or 25 cents

12(.10)=$1.2

4(.25)=1

the equations would be

.25(x)

.10(x)

and if you need them combined it would be

.25(x) + .10(x)

Solve the equation x² + 6x + 1 = 0. give your answer to two decimal places

Alexandra [31]

Answer:

x ≈ - 5.83 , x ≈ - 0.17

Step-by-step explanation:

x² + 6x + 1 = 0 ( subtract 1 from both sides )

x² + 6x = - 1

Using the method of completing the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(3)x + 9 = - 1 + 9

(x + 3)² = 8 ( take square root of both sides )

x + 3 = ± $\sqrt{8}$ ( subtract 3 from both sides )

x = - 3 ± $\sqrt{8}$

Then

x = - 3 - $\sqrt{8}$ ≈ - 5.83 ( to 2 dec. places )

x = - 3 + $\sqrt{8}$ ≈ - 0.17 ( to 2 dec. places )
