Answer: x = \sqrt{320}, or 17.8885438

Step-by-step explanation:

According to the pythagorean theorem, a^2 + b^2 = c^2.

As such, 4^2 + x^2 = (4sqrt5)^2

16 + x^2 = 80

x^2 = 64

x = 8.

Thus, the dashed line in the center is 8.

Simply plug this into the pythagorean theorem as well.

8^2+16^2=p^2

p^2 = 320

p = 17.8885438, or sqrt 320

Solve for x. 4(7x−3)−6=6−4(3x−7) Enter your answer in the box.
olasank [31]

4(7x−3)−6=6−4(3x−7)

Distributive property

28x - 12 - 6 = 6 - 12x + 28

28x - 18 = -12x + 34

28x + 12x = 34 + 18

40x = 52

   x = 52/40

   x = 13/10

or

   x = 1 3/10 (mixed number:  1 and 3/10)

There is a rectangular prism that can fit 28 cubes with edge lengths of 1/2 inch each. What is the volume of this rectangular pr
siniylev [52]

Answer:

3.5 inch^3

Step-by-step explanation:

Volume of cube: V = s^2,

where V = volume, and s = length of side or edge.

The volume of the prism is the same as the volume of 28 cubes with edge length of 1/2 inch. To find the volume of the prism, find the volume of one cube and multiply by 28.

volume of prism = 28 * volume of cube

volume of prism = 28 * (1/2 inch)^3

volume of prism = 28 * 1/8 inch^3

volume of prism = 3.5 inch^3
