Answer:

x²- √3 x +1/2

Step-by-step explanation:

To write a quadratic equation with roots only:

x² -(sum of the roots)x+(product of roots)

x²-((√3-1/2)+(√3+1/2)x + ((√3-1/2)(√3+1/2)

x² -(2√3)/2 + ( 9-1)/4

x²- √3 x +1/2

2. One number is eight more than another of
Jlenok [28]

Answer:

10 and 18

Step-by-step explanation:

a + 2b = 46

A + 2(b+8) = 46

b + 2b + 16 = 46

3b+ 16 = 46

3b = 30

b = 10

That’s the first number.

b is 10 so a is 10+8 = 18 because it’s 8 more then the other number.

b + 2a = 46

(10) + 2(18) = 46

10 + 36 = 46

46 = 46

Shelby is an entrepreneur who has decided to open a small advertising firm. She rents office space at a cost of $25,000 per year
mestny [16]

Answer:

$ 125,000

Step-by-step explanation:

Given,

The amount of rent = $ 25,000,

The salary of assistant = $ 30, 000

Expenses = $ 20,000,

Also, her best alternative is to work elsewhere and to earn a salary of $50,000 per year.

Thus, the investment in the firm = 25000 + 30000 + 20000 + 50000

= $ 125,000,

Now, if she earns zero economic profit,

Then her revenue = investment

= $ 125,000

The measure of angle x is 18 more than 3 times the measure of its complement.
Alex
Complementary angles = two angles that add to 90° complement each other.


So, angle x = 3y+18
y= complementary angle
(3y + 18) + y =  90
4y+18 = 90
4y=72
y=18°

x= 3y+18
x= 3(18) +18
angle x = 72°
