Volume of a Rectangular Prism Formula: V = lwh

  • <em>l</em> is length
  • <em>w</em> is width
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>l</em> = 8 ft

<em>w</em> = 4 ft

<em>h</em> = 4 ft

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Rectangular Prism Formula]:               V = (8 ft)(4 ft)(4 ft)
  2. Multiply:                                                                                                             V = (32 ft²)(4 ft)
  3. Multiply:                                                                                                             V = 128 ft³

A rectangle has an area of 96 cm2 The length of the rectangle is 4 cm longer than the width. Work out the length and width of th
Svetach [21]
Area of a rectangle: 2(L+W)
length: 4+W

Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm

Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm

• The length is 26cm and width is 22 cm.

Which points are on the graph of the equation - 3x + 6y + 5 = -7?
ludmilkaskok [199]

Answer:

C and E

Step-by-step explanation:

To solve this problem, let's plug in each coordinates into the equation.

A:

  • -3(-3) + 6(6) + 5 = -7
  • 9 + 36 + 5 = -7
  • 50 = -7
  • 50 \neq -7
  • A. cannot be the answer, as 50 does not equal -7.

B:

  • -3(-2) + 6(0)+5=-7
  • 6+0+5=-7
  • 11=-7
  • 11\neq -7
  • B. cannot be the answer, as 11 does not equal -7.

C:

  • -3(0) + 6(-2) + 5 = -7
  • 0 - 12 + 5 = -7
  • -12 + 5 = -7
  • -7 = -7
  • C. can be the answer, as -7 does equal -7.

D:

  • -3(6)+6(-3)+5=-7
  • -18-18+5=-7
  • -36+5=-7
  • -31\neq -7
  • D. cannot be the answer, as -31 does not equal -7.

E:

  • -3(8) + 6(2) + 5 = -7
  • -24 + 12 + 5 = -7
  • -12 + 5 = -7
  • -7 = -7
  • E. can be the answer, as -7 does equal -7.

emmainna [20.7K]

Answer:

A

Step-by-step explanation:

-6(4 - x) <= -4(x + 1)

-24 + 6x <= -4x - 4

-24 + 10x <= -4

10x <= 20

x <= 2
