Answer:

k = 11.87

Step-by-step explanation:

Because the two expressions should be equivalent, set the two expressions equal to each other.

-10.5x+k=-2.1(5x-3.7)+4.1

Begin simplifying the equation and solve for k.

-10.5x+k=-10.5x+7.77+4.1 (distributive property)

-10.5x+k=-10.5x+11.87 (combine like terms - 7.77 + 4.1)

k = 11.87 (add 10.5x to both sides to combine like terms -- the x values cancel out because -10.5x+10.5x = 0.  Therefore, you are left with k = 11.87)

Hi there!

\large\boxed{\text{33 in}^2}

Find the total area by breaking the figure into two rectangles, one trapezoid, and one triangle.

Rectangles:

A = l × w

A = 2.75 × 4 = 11 in²

Solve for the other rectangle's length by subtracting from the total:

12 - 2 - 3 - 4 = 3

A = 3 × 3 = 9 in²

Total rectangle area: 11 + 9 = 20 in²

Trapezoid:

A = 1/2(b1 + b2)h

A = 1/2(4.25 + 2.75)3 = 21/2 = 10.5 in²

Triangle:

A = 1/2(bh)

A = 1/2(2.5 · 2) = 2.5 in²

Add up all of the areas:

20 + 10.5 + 2.5 = 33 in²

Mario has a rectangular prism completely filled with sand that has a base area of 85 cm² and a height of 15 cm. Mario pours all
just olya [345]

The base area of this second rectangular prism is 51 cm²

The rectangular prism completely filled with sand has a base area of 85cm² and height of 15cm .

<h3></h3><h3> volume of a rectangular prism</h3>
  • volume = Bh

where

B = base area

h = height

Since the first rectangular prism was completely filled with sand and it completely filled the second rectangular prism, it means they both have the same volume.

Therefore,

volume of the first rectangular prism = volume of the second rectangular prism.

  • volume  = Bh
  • volume = 85 × 15
  • volume = 1275 cm³

Therefore, the base area of the second rectangular prism can be calculated as follows:

volume = Bh

1275 = 25B

B = 1275 / 25

B = 51 cm²

The remainder of the given expression will be 66.

<h3>What is division?</h3>

Division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic.

The given polynomlal x⁴+3x³-6x²-12x-8 will be divided by x-3 so we need to find the remainder:-

x-3) x⁴+3x³-6x²-12x-8 ( x³-6x²+12x+24

      x²-3x³

    _______________

            6x³-6x²-12x-8

            6x³-18x²

________________________

                   12x²-12x-8

                   -12x²-36x

  _____________________

                            24x-8

                            24x-72

_______________________

                                    66

Hence the remainder of the given expression will be 66.
