What is the simplest form of (5x-8)(2x+4)

1 answer:

8 0

Let's solve step by step

So all we need to do is simplify the equation

(5x − 8)(2x + 4)

= (5x + −8)(2x + 4)

= (5x)(2x) + (5x)(4) + (−8)(2x) + (−8)(4)

= 10x^2 + 20x − 16x − 32

= 10x^2 + 4x − 32

Therefore the simplified form of this is 10x^2 + 4x − 32

Answer: OPTION D

Step-by-step explanation:

The formula for calculate the surface area of a rectangular prism is:

$SA_{rp}=2(wh+lw+lh)$

Where w is the width, h is the height and l is the length.

You can see in the figure attached that:

l=3.4ft

w=3ft

h=4.1ft

Therefore, when you substitute these values into the formula you obtain that the surface area is:

$SA_{rp}=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^{2}$

Consider parallelogram △MNOP shown above.

Nina [5.8K]

To find the length of the sides of this parallelogram, we just have to calculate the length of each side and then proceed to find the perimeter.

The perimeter of the parallelogram is 13 units.

<h3>Perimeter of a Parallelogram</h3>

To calculate the perimeter of a parallelogram, we need the values of the length of the sides. However, if we have the details of two opposite sides, we can find the perimeter of the parallelogram because opposite sides are equal.
