Answer:

Answer: -30

Step-by-step explanation:

${(8 - 10)}^{2} - 30 \div 5 \times 6 + 2$

BODMAS

let's first solve the bracket:

$= {( - 2)}^{2} - 30 \div 5 \times 6 + 2 \\ = 4 - 30 \div 5 \times 6 + 2$

then let's divide:

$= 4 - (30 \div 5) \times 6 + 2 \\ = 4 - 6 \times 6 + 2$

then let's multiply:

$= 4 - (6 \times 6) + 2 \\ = 4 - 36 + 2$

simplify:

$= - 30$

Martha is buying a house for $107,820. She is making 15 percent down payment and financing the remainder at 6.5 percent for 25 y

stellarik [79]

Given:
Total price : 107,820
down payment 15% of the total price.
financing the remainder at 6.5% for 25 years.

How much is she financing? She will finance 85% of the total price.

107,820 * 15% = 16,173
107,820 - 16,173 = 91,647

or
107,820 * (100-15)% = 107,820 * 85% = 91,647

Hey can you please help me posted picture of question :)

Answer:
The roots are: $\frac{ \sqrt{3} + 3 }{2}$ and $\frac{- \sqrt{3} + 3 }{2}$

Explanation:
First, we would need to put the equation is standard form which is as follows:
ax² + bx + c = 0
This can be done as follows:
4x² - 12x + 9 - 3 = 0
4x² - 12x + 6 = 0

By comparison, we would find that:
a = 4
b = -12
c = 6

To get the roots, we would substitute in the quadratic formula shown in the attached image.

Doing this, we would find that:
either x = $\frac{ \sqrt{3} + 3 }{2}$

or x = $\frac{- \sqrt{3} + 3 }{2}$

Hope this helps :)
