Please help me, i don’t understand this question nor how to do it !!!!
Fantom [35]

Step-by-step explanation:

See attached picture.

First, compare the highest term of the dividend (x²) to the highest term of the divisor (x).  We need to multiply the divisor by x.

When we do that, we get x² + 5x.  Subtracting this from the dividend, we get -9x + 11.

Now repeat the process.  Compare the highest term of the new dividend (-9x) to the highest term of the divisor (x).  We need to multiply by -9.

When we do that, we get -9x − 45.  When we subtract from the new dividend, we get 56.

So the quotient is x − 9, and the remainder is 56.

Tracy needs to find the length and width of the equipment room where she works. The room is 2 meters longer than it is wide. The
Alekssandra [29.7K]

Answer:

The answer to your question is: width = 3 meters

Step-by-step explanation:

Data

Perimeter = 16 meters

The room is 2 meters longer than its width, then   length = width + 2

Perimeter = 2 length + 2 width

   16 =  2(width + 2) + 2 width

    16 = 2 width + 4 + 2 width

   16 = 4 width +4

   16 - 4 = 4 width

    12 = 4 width

    12/4 = width

     3 = width  

length = 3 + 2 = 5 meters

What is the orthocenter of a triangle with vertices A(−3,−2)A(−3,−2), B(−2,2)B(−2,2), and C(2,−2)C(2,−2)?
ExtremeBDS [4]

A(−3,−2), B(−2,2), C(2,−2)

The orthocenter is the meet of the altitudes. We see AC is parallel to the x axis so the perpendicular x=-2 is the altitude through B.

Between A and B we have slope (2 - -2)/(-2 - -3) = 4 so perpendicular slope -1/4 through C(2,-2):

y+2 = -\frac 1 4 (x - 2)

For the y coordinate of the orthocenter we substitute in x=-2.

y+2 = -\frac 1 4(-2 - 2) = 1

y = -1

So the orthocenter is (x,y)=(-2,-1)

Answer: (-2,-1)
