Answer:
[tex]m = 3 \sqrt{12} [/tex]
[tex]n = 6[/tex]
Step-by-step explanation:
n=1/2 of 12 according to the rule:
right triangle the side opposite the 30 degree angle is half the length of the hypotenuse.
so n=12/2=6
and now we will need Pythagorean theorem : the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
so
[tex] {m}^{2} + {n}^{2} = {12}^{2} [/tex]
now lets put numbers on formula
[tex] {m}^{2} + {6}^{2} = {12}^{2} [/tex]
from this formula m=
[tex]m = \sqrt{ {12}^{2} - {6}^{2} } = \sqrt{144 - 36} = \sqrt{108} = 3 \sqrt{12} [/tex]

Which of the following isolates r correctly?
4r - 6 = 2(n + 3)
Answer:
r = 1/2n + 3
Step-by-step explanation:
Are there answer choices to choose from?
This is how you would isolate the r:
4r = 2n + 6 + 6 so 4r = 2n + 12
Solve for r by dividing both sides by 4 so r = 1/2n + 3
Answer:
-2=2n+6
2n=2-6
2n=-4
n=-2
Tyler tried to solve an equation step by step
3(x +4)=-18
Answer:
x = -10
3(x + 4) = -18
3x + 12 = -18
3x + 12 = -18
3x = -18-12
3x = -30
x= -30/3
x = -10
Step-by-step explanation:
[tex]3(x + 4) = - 18 \\ (x + 4) = \frac{ - 18}{3 } \\ (x + 4) = - 6 \\ x = - 6 - 4 \\ x = - 10[/tex]

Write the equation of the line parallel
to y = 4 /5x + 4/5 that passes through the point ( -6,6).
Step-by-step explanation:
Here, slope= 4/5 , As y= mx+c
according to formula, y-y1= m(x-x1)
y-6= 4/5(x+6)
5/4 (y-6)= x+6
5/4y - 15/2= x+6

A square has an area of 12x^2 square feet. What is the length of its sides?
A rectangular chocolate bar is made of equal squares. Irena breaks off two complete strips of squares and eats the 12 squares she obtains. Later, Jack breaks off one complete strip of squares from the same bar and eats the 9 squares he obtains. How many squares of chocolate are left in the bar?
Answer:
There are three more square chocolates left
Step-by-step explanation:
We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)
The number of Squares of chocolate left in the bar is; 15 squares
What is the amount of squares left?
A square has 4 equal sides and since one row contains 6 squares because irena ate 2 complete rows that had 12 squares.
It means that each of the vertical height must also contain 6 squares as well.
Now, two rows are gone and so we now have 4 rows with vertical height of 4 squares. That is 24 squares left.
Now, Jack ate 9 squares and so;
Amount of squares left = 25 - 9 = 15
