Answer:

4m+8n -4p

Step-by-step explanation:

hello

you can just sum like a normal addition, just put  similar terms on each other

       5m   + 3n    +p

                +3n    -5p  (second expression)

        -m    +2n            ( third expression)

    _____________

 (5-1)m  (3+3+2)n+(1-5)p = 4m+8n -4p

I hope it helps you

Have a great day

A. Is this mapping diagram a function? Why or why not?
nikitadnepr [17]

Answer:

40--C   A ---is not[figure it out in your own words,your teacher might suspect something] and B---times 40

Step-by-step explanation:

b--40+40=80   80+40=120 and 120+40=160                A=subtract 40 from all the other answers such as 40-160=120       40-120=80  and 40-80=40

A hyperbola centered at the origin has a vertex at (0,−40) and a focus at (0, 41).
aniked [119]

\frac{(x-h)^{2} }{a^{2} } - \frac{(y - k)^{2} }{b^{2} } = 1

\frac{(x-0)^{2} }{40^{2} } - \frac{(y - 0)^{2} }{b^{2} } = 1

a² + b² = c²

40² + b² = 41²

         b² = 41² - 40²

         b² = 1681 - 1600

         b² = 81

         b = 9

slope (m) of asymptote = +/-\frac{y}{x} = +/-\frac{b}{a} = +/-\frac{9}{40}

y-intercept (b) = 0 since the center is at the origin

Answer: y = \frac{9}{40}x and y = -\frac{9}{40}x

Cynthia Bech want to buy a rug for a room that i 20 ft wide and ft long. She want to leave a uniform trip of 29 floor around the
Hoochie [10]

On solving the question, we got that - The dimensions of the rug should be 18 feet and 24 feet

<h3>What is area of rectangle?</h3>

By multiplying the rectangle's length by its breadth, we may get its area.

Equiangular quadrilaterals, like rectangles, are known in this way. This is so because a rectangle is a four-sided quadrilateral shape with parallel sides that are equal to one another and four corners with 90o angles. Rectangles are sometimes known as equiangular quadrilaterals since all of its angles are 90 degrees.

the parameters provided;

The room is 20 feet by 26 feet in size.

432 feet2 is the largest area rug she can afford.

If the floor will be a uniform stripe around the rug, then each dimension should have its uniform extra length of floor =  (y).

Area = Length X Width\\432 = ((20=y) X (26-y)\\432 = 520 - 20y - 26y + y^2\\y^2 - 46y+88=0\\

here, a= 1, b= -46, c =88

y = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a} \\\\

y = \frac{-(-46) +/- \sqrt{(-46)^2 - 4X1X88} } {2} \\\\y = 44 \\or\\ y =  2

Therefore, Length = 20-2 = 18 ft

and width = 26-2 = 24ft
