Answer:

36

Step-by-step explanation:

Well, we can do this 2 ways: Distribute first, or do it last.

Distribute First:

12b-24=

12(5)-24=

60-24=

36

Distribute last:

6(2(5)-4)=

6(10-4)=

Now you can take this two ways.

Distribute:

60-24=36

OR

Parenthessess: (I dont know how to spell.)

6(6)=36

I’m kinda stuck on here on how to do this .... how am I suppose to go down again if it’s not gonna be on the line.
mars1129 [50]

To graph the new shape, you must move each vertex down 3 units. This causes Q to become (1, 0), L to become (5, -2), and Q to become (1, 0). These values can be found by simply counting down by three for each point.

Find cot θ if csc θ = negative square root of thirty seven divided by six and tan θ > 0.
Ket [755]
You can use the trigonometric identity  1+\cot^2{x}=\csc^2{x}.

1+\cot^2{\theta}=(\frac{-\sqrt{37}}{6} )^2 \\ 1+\cot^2{\theta}=\frac{37}{36} \\ \cot^2{\theta}=\frac{1}{36} \\
\cot{\theta}=\frac{1}{6}

The requirement that \tan{\theta}\ \textgreater \ 0 eliminates -1/6 from being another solution.

Solve the following quadratic equations by completing the square.<br><br> y^2-14y+48=0
NISA [10]

Answer:

  y = 6 or 8

Step-by-step explanation:

1. Subtract the constant:

  y^2 -14y = -48

2. Add the square of half the y-coefficient:

  y^2 -14y +49 = -48 +49

Write as a square, if you like:

  (y -7)^2 = 1

3. Take the square root:

  y -7 = ±√1 = ±1

4. Add the opposite of the constant on the left:

  y = 7 ±1  =  6 or 8

The solution is y = 6 or y = 8.

In isoceles triangle the length of a leg is 17cm, and the base is 16cm. Find the length of the altitude to the base
Elan Coil [88]

This triangle has base 16 therefore the sides must be 17cm and 17 cm

When we make a altitude it divides it into two right triangles and there is a property in which the altitude of the isoceles triangle divides the base in 2 equal halves

So the side of the right triangle will be x , 8 , 17

Using pythgoreus theorem

x²+8²=17²

x = √225

x = 15

So the altitude is 15 cm
