Answer:

x= ± $3\sqrt{2} /2$ +2

Step-by-step explanation:

Use the formula ( b/2) ^2 in order to create a new term. Solve for x by using this term to complete the square.

Simplify the following expression into the form a+bi where a and b are rational numbers

hoa [83]

- 28 - 40i

note that i² = (√-1)² = - 1

expand product of factors using FOIL

= - 6 - 6i - 14i - 14i² - 20i + 36i²

= - 6 - 6i - 14i + 14 - 20i - 36

= - 28 - 40i

Varia is studying abroad in Europe. She is required pay $3,500 (in US dollars) per year to the university, however, she must pay

sleet_krkn [62]

Answer:

213 euros per month

Step-by-step explanation:

1dollar = 0.7306euros

thus $3,500 dollars can be found by a rule of three

dollar euro

1 ⇒ 0.7306

3500 ⇒ x

we find x as follows:

$x=\frac{0.7306*3500}{1} = 2,557.1$ euros

She will pay 2,557.1 euros per year.

Dividing between the 12 months of the year:

$\frac{2,557.1}{12}=213.1$

Rounding to the nearest whole euro she will pay 213 euros per month.

Solve the equation. Round answers to the nearest hundredth when necessary. 4x^2 = 100

Westkost [7]

To solve 4(x-2)^2 = 16
divide each side by 4 to have (x-2)^2 = 4
take the square root of both sides
x-2 = -2 or x-2 = 2
add 2 to each side
x = 0 or x = 4
4 ( 0-2)^2 = 16
4 (-2)^2 = 16
4 (4) = 16 true
4 ( 4-2)^2 = 16
4 (2)^2 = 16
4 (4) = 16 true.
the values for x are 0 and 4.
