Answer:

C. x > 225 and x < 325

Step-by-step explanation:

460 < 2x + 10 =>

450 < 2x

225 < x

x > 225

and

2x + 10 < 660 =>

2x < 650

x < 325

So x > 225 and x < 325.

What is the stem-and-leaf plot for
Verdich [7]

The stem-and-leaf plot for 29,22,21,6,13,6,17,29,26,9,16,10,25,3,2,23,13,10,7,16,29,30,4,11,7,28,27,22,10 is shown in the image attached below (see attachment).

<h3>What is a Stem-and-leaf Plot?</h3>

A stem-and-leaf plot is a table which is used to display a set of data in such a way that, on the left we have the "stem" which displays the first digit or digits of a data value.

On the right, we have the 'leaf' which displays the last digit of the data value.

For example, if we are to represent "25" and "26" on a stem-and-leaf plot, we would have: 2 | 5, 6.

Therefore, the stem-and-leaf plot for 29,22,21,6,13,6,17,29,26,9,16,10,25,3,2,23,13,10,7,16,29,30,4,11,7,28,27,22,10 is shown in the image attached below (see attachment).

Answer:

  • <u>B) A = 2x² - 8x + 8</u>

Step-by-step explanation:

<u>Area of a triangle</u>

  • A = 1/2bh

Here,

  • b = 2x - 4
  • h = 2x - 4

<u>Solving</u>

  • A = 1/2 (2x - 4) (2x - 4)
  • A = 1/2 (2x - 4)²
  • A = 1/2 (4x² - 16x + 16)
  • <u>A = 2x² - 8x + 8</u>
