Answers:

  • x = 7
  • Area of shaded region = 162 square units

You may need to leave off the "square units" portion.

=============================================

Explanation:

For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.

L = 3x

W = x+5

The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.

P = 2(L+W)

2(L+W) = P

2(3x+x+5) = 66

2(4x+5) = 66

8x+10 = 66

8x = 66-10

8x = 56

x = 56/8

x = 7

-------------------

Now that we know x, we can find the area of the rectangles.

As you probably can guess, the shaded region is the difference of the two areas.

A = area of larger rectangle

A = (length)*(width)

A = (3x)*(x+5)

A = (3*7)*(7+5)

A = 252

B = area of smaller rectangle

B = (x+3)*(x+2)

B = (7+3)*(7+2)

B = 90

C = area of shaded region

C = A - B

C = 252 - 90

C = 162 square units is the area of the shaded region.

Solve the equation for x. 1 3 (6x − 9) = −33
KIM [24]

Answer:

<u>x = 1.07</u>

Step-by-step explanation:

13 ( 6x - 9) = -33

78x  - 117 = -33            ( opening brackets and multiplying )

78x  = 84                     ( - 117 taken to the other side makes it positive)

  x  =  84 / 78

  x  =  <u>1.07</u>

mariarad [96]

Answer: (0.685, 0.735)

Explanation:

First, we will compute the confidence level of the given:

\text{ Confidence Level }=\frac{36}{40}\times100\%=90\%

They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.

The confidence interval would then be:

\begin{gathered} (p-E,p+E) \\ =(0.71-0.025,0.71+0.025) \\ =(0.685,0.735) \end{gathered}

Therefore, the confidence interval would then be (0.685, 0.735)
