Mathematics
1 answer:
xxMikexx [17]2 years ago
5 0

Answer:

  • 8x² + 8x - 2

Step-by-step explanation:

<u>We know that:</u>

  • Perimeter of a rectangle = Sum of all its sides
  • Length of rectangle = 4x² - x + 2
  • Width of rectangle = 5x - 3

To find the perimeter, we need to use the equation "Perimeter of a rectangle = Sum of all its sides".

<u>Solution:</u>

  • Perimeter of a rectangle = Sum of all its sides
  • => 2[{4x² - x + 2} + {5x - 3}] = Perimeter
  • => 2[4x² - x + 2 + 5x - 3] = Perimeter
  • => 2[4x² + {-x + 5x} + {2 - 3}]
  • => 2[4x² + 4x - 1]
  • => 8x² + 8x - 2

Hence, the perimeter of the rectangle is 8x² + 8x - 2.

A rectangular prism has a length of 12 centimeters, a width of 6 centimeters, and a height of 9 centimeters. A cross section is
Klio2033 [76]

Answer:

<h2>The perimeter of the cross section is 30 centimeters.</h2>

Step-by-step explanation:

In this problem we have the intersection of a rectangular prism an a plane.

The dimensions of the rectangular plane are

l=12cm\\w=6cm\\h=9cm

Assuming the plane is cutting the prism horizontally, the cross section would have dimensions

w=6cm\\l=9cm

Because only the height would be cut.

So, the perimeter of the rectangle cross-section is

P_{cross}=2(l+w)=2(6+9)=2(15)=30cm

Therefore, the perimeter of the cross section is 30 centimeters.
