Answer:

A) x = 6 y = 6√3

Step-by-step explanation:

30-60-90 Triangle rule states that the hypothesis is 2x, the short leg is x, and the long leg is x√3. So, the short leg is 12/2 = 6, and the long leg is 6√3.

Answer:

a)2x-3y

b)4(9a-4)

Step-by-step explanation:

we want to expand the following expression:

$\displaystyle - \frac{1}{4} ( - 8x + 12y)$

well to do so we consider distributive property thus distribute:

$\displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y)$

reduce fraction which yields:

$\displaystyle - \frac{1}{4} (- 8x )+ - \frac{1}{4}( 12y) \\ \\ \displaystyle 2x + ( - 3y)$

simplify Parentheses:

$\displaystyle \boxed{ 2x - 3y}$

in the expression there's a common factor of 4 therefore factor it out:

$\displaystyle 9.4a - 4.4 \\ \\ \displaystyle \boxed{4(9a - 4)}$

I believe the answer is 64
First break it off into 2 rectangles on is 4 width and 10 length other is 8 length and 10 width. Then multiple to find area 10•4=40 8•3=24 then add 40+24= 64
