There would be 14 inches on both sides.

{[(3 * 12) + 6 ] -14} ÷ 2
{[ 36 + 6 ] - 14 } ÷2
{ 42 - 14 } ÷2
28 ÷2

PLS HELP WITH THIS ONE
olga2289 [7]

Answer:

460 ft^2 of carpet will be replaced

Step-by-step explanation:

You need to find the area of the room and then take away the area of the six bookcases

<u>Area of the room</u>

20*20=400ft^2

35-20=15ft

(15*20)/2=150ft^2

400+150=550ft^2 total room area

<u>Area of bookcases</u>

2.5*6*6=90ft^2 total bookcase area

<u>room area - bookcase area = carpet area</u>

550-90=460ft^2

What is the result of isolating y^2 in the equation below (x+6)^2+y^2=1​
katrin [286]

Answer:

(x+6)^2 + y^2 = 1 then isolate y^2  by subtracting (x +6)^2 from both sides, we get

               

                y^2 = 1 - (x + 6)^2

expanding the right side, we now have

                y^2 = 1-(x^2 + 12x +36)

          y^2 = 1-x^2-12x -36

          y^2 = -x^2 -12x - 35  therefore the solution is  choice A

The point P(8, −3) lies on the curve y = 3/(7 − x). (a) If Q is the point (x, 3/(7 − x)), use your calculator to find the slope
yan [13]

Answer:

Slope of the line PQ is -63.434948.

Step-by-step explanation:

Given that,

The point P(8,-3) lies on the curve y=\frac{3}{7-x}.

If Q is the point lies on (x,\frac{3}{7-x} ).

To find:- Find the slope of line PQ.

So,  

The coordinates of point Q when it lies on (x,\frac{3}{7-x} )

        if x=1 then y= \frac{3}{7-1} =\frac{3}{6} =\frac{1}{2}

       So,   Q ≡ (1,\frac{1}{2} ) and many points can be calculated by given Equation.

Using the formula when two points (x_{1} ,y_{1} ) \& (x_{2}, y_{2}  ).

                Slope=Tan\theta = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Then, substituting the coordinates we get,

             Slope = \frac{1-8}{\frac{1}{2}-(-3) }

             Slope = \frac{-7}{\frac{1}{2}+3 } = \frac{-7}{\frac{7}{2} }

             Slope = \frac{-14}{7}=-2

              tan\theta=-2   ⇒  \theta = tan^{-1} (-2)

               \theta= -63.434948

Therefore,

Slope of the line mPQ is -63.434948.
