Answer:

The value of x is -2.828 or 2.828

Step-by-step explanation:

In order to eliminate of square of x, you have to square root both sides :

{x}^{2}  = 8

\sqrt{ {x}^{2} }  = ± \sqrt{8}

x =  \sqrt{8}  \\ x = 2 \sqrt{2}  \: or \: 2.828

x =   -  \sqrt{8}  \\ x =  - 2 \sqrt{2}  \: or \:  - 2.828

What is the area of a trapezoid with coordinated (0.0), (1,3), (4,3), (2,0)? (no picture given)
Orlov [11]

The area of the trapezoid, to the nearest whole number is: D. 8 units²

<h3>What is the Area of a Trapezoid?</h3>

Area of trapezoid = 1/2(a + b)h, where:

  • h = height of trapezoid
  • a and b = lengths of the bases of the trapezoid.

Using the coordinates of the trapezoid, (0,0), (1,3), (4,3), (2,0), the points have been plotted on a coordinate plane as shown in the image attached below, and we have the following dimensions of the trapezoid:

  • h = 3 units
  • a = 3 units
  • b = 2 units

Area of the trapezoid = 1/2(a + b)h = 1/2(3 + 2)3

Area of the trapezoid = 7.5 ≈ 8 units²

This list shows the prices for an ice cream sundae at 5 different ice cream shops. What is the median price of the sundaes? $4.8
Margarita [4]
To find median, you must first order the numbers from least to greatest.
$3.85, $4.79, $4.85, $5.38, $5.96
Since there is an odd amount of numbers, the median is the middle number.
In this case, the number in the middle is $4.85.
This means that the median is $4.85.

Hope this helps!
