How do you simplify this ? 8(x - 4) - 6(x - 1) + 9x

Neporo4naja [7]

$8(x-4)-6(x-1)+9x\\\\=8\cdot x+8\cdot(-4)-6\cdot x-6\cdot(-1)+9x\\\\=8x-32-6x+6+9x\\\\=(8x-6x+9x)+(-32+6)\\\\=\boxed{11x-26}$

A square region with perimeter 60 inches is made with square inch tiles. Bob removes one tile from the square and rearranges the

icang [17]

Answer:

60 inches

Step-by-step explanation:

The perimeter will be minimized when the tiles are rearranged to form a rectangle with dimensions as close to each other as possible.

<h3>Rectangle dimensions</h3>

The square has a side length of ...

P = 4s ⇒ s = P/4 . . . . . P is perimeter, s is side length

(60 in)/4 = 15 in . . . . length of the side of the square

The square has an area of ...

A = s²

A = (15 in)² = 225 in²

When 1 tile is removed, the resulting area, in square inches, is ...

A = 225 -1 = 15² -1² = (15 -1)(15 +1) = 14×16

<h3>Perimeter</h3>

The perimeter of a rectangle is given by ...

P = 2(L+W)

For this rectangle, the perimeter is ...

P = 2(14 in + 16 in) = 2(30 in) = 60 in

The perimeter of the rectangle is 60 inches.

Which ordered pair makes both inequalities true?

kvasek [131]

Answer:

(3, 0)

Step-by-step explanation:

Given the inequality y > -2x + 3 and y ≤ x - 2

The graph of the inequalities are plotted using the geogebra graphing online calculator.

The portion of the graph that is shaded with dark blue, represents the portion that supports the equation.

All the ordered pair points given in the question are also labelled in the graph.

From the graph we can see that only point (3, 0) falls in the area that supports the equation. Hence (3, 0) makes both inequalities true.

Denise bought a box of 560 pieces of candy.4/5 of the pieces of the candy were fruity and 1/4 of the remaining pieces of candy w

Liula [17]

Answer:

<em>Number of Other flavor candy is 84.</em>

Step-by-step explanation:

Given that

A total of 560 pieces of candy are there in the box.

$\frac{4}{5}$ of the pieces are fruity.

Number of Fruity pieces:

$\dfrac{4}{5} \times 560\\\Rightarrow 4 \times 112 =448$

Now, remaining pieces = Total pieces - Fruity pieces

remaining pieces = 560 - 448 = 112

Also given that $\frac{1}4$ of the remaining pieces are mind.

Number of mint pieces:

$\dfrac{1}{4}\times 112 = 28$

Other flavors remaining = Total pieces - Fruity pieces - Mint pieces

Other flavors remaining = 560 - 448 - 28

Other flavors remaining = 112 - 28 = <em>84</em>

<em>Number of Other flavor candy is 84.</em>
