Step-by-step explanation:

Since the powers are equal you can write the expression as a one root

But we cannot get 9 out since the square root of 9 is 3 which is second power (3^2) and the power of the root is 4

Holpe this helps, if you need further explanation you can ask.

Suppose that on a coordinate plane a hexagon is reflected across the x-axis. Compare the area of the original hexagon to the are
kap26 [50]

Reflection along x-axis is just a swapping of left and right sides. It does not change the size or area of the hexagon.

Hence, the correct option is B.

Find the value of b. Then find the angle measures of the pentagon.
melamori03 [73]

Answer:

b = 90

Step-by-step explanation:

Sum the interior angles of the pentagon and equate to 540

Starting from the top and going clockwise

b + b + 45 + 90 + 2b - 90 + \frac{3}{2} b = 540 ← simplify left side

\frac{11}{2} b + 45 = 540 ( multiply through by 2 to clear the fraction )

11b + 90 = 1080 ( subtract 90 from both sides )

11b = 990 ( divide both sides by 11 )

b = 90

Thus

b + 45 = 90 + 45 = 135

2b - 90 = 2(90) - 90 = 180 - 90 = 90

\frac{3}{2} b = \frac{3}{2} × 90 = 135

The angle measure from the top clockwise are

90°, 135°, 90°, 90°, 135°

Explain the difference between using area and volume with 2-D and 3-D figures.
Marianna [84]

The difference between Area and Volume lies in the fact that the former relates to plane shapes while the latter takes the concept of solid shapes into account.

<h3>What is the difference between Area and Volume?</h3>

The distinctive characteristic of area is the space occupied by a two-dimensional, 2D flat object in a plane while Volume on the other hand is defined as the space covered by a three-dimensional, solid object. The area is quantised in square units while the volume is quantised in cubic units.
