4 x^{2} -y^{2} -6y-9 \\ 4 x^{2} = y^{2} +6y+9 \\ 4 x^{2} =(y+3)(y+3) \\  \sqrt{ 4x^{2} } = \sqrt{(y+3)(y+3)} =\\2x=y+3\\2x-3=y

What steps should be taken to calculate the volume of the prism? Select three options. A rectangular prism with a length of 9 an
fgiga [73]

The steps to be taken to determine the volume of the rectangular prism are:

Use A = bh to find the area of the base.

Use V = Bh to find the volume of the prism.

Volume of the prism, V = (228)(6) = 1,368 feet cubed.

<h3>How to Find the Volume of a Rectangular Prism?</h3>

A rectangular prism has a height, base, and width. The volume of the rectangular prism can be found by using the following steps:

  • Find the base area of the rectangular prism using the formula, A = bh, where b is the base length and h is the height of the base.
  • Then, find the Volume using the formula, V = Bh, where B is the base area and h is the height of the prism.

Parameters are:

Length of prism = 9 and one-half feet,

Width of prism = 24 feet,

Height of prism = 6 feet

Given the dimensions of the rectangular prism above, do the following:

Find the area of the base of the rectangular prism:

Area of base = (9 1/2)(24) = 228 cm²

Find the Volume of the prism using V = Bh :

Volume of the prism = (228)(6) = 1,368 feet cubed.

Therefore, the steps to be taken to determine the volume of the rectangular prism are:

  • Use A = bh to find the area of the base.
  • Use V = Bh to find the volume of the prism.
  • Volume of the prism, V = (228)(6) = 1,368 feet cubed.

In the fifth grade class, 4/5 of the girls have brown hair. Of the brown-haired girls, 3/4 of of them have long hair. Of the gir
irinina [24]
As a tip, remember that whenever a problem says "of," multiply. So if you want to find brown hair and long hair, multiply, 4/5*3/4.
4/5*3/4=12/20=3/5
Part A: 3/5 of the girls in the fifth grade class have long brown hair.

If they have long brown hair and green eyes, multiply 3/5*1/3. Since it is all three, get the answer from above and multiply it by 1/3.
3/5*1/3=3/15=1/5
Part B: 1/4 of the girls in the fifth grade class have long brown hair and green eyes. 

Hope this helps! If you have any questions, just ask!
