Which expression is equivalent to-3x(x-4)-2x(x+3)

Answers

Answer:

-5x² +6x

Explanation:

The given expression is :

-3x(x-4)-2x(x+3)

It can be done as follows :

-3x(x-4)-2x(x+3) = (-3x)(x)-(-3x)(4) - 2x(x)-2x(3)

= -3x² +12x -2x² -6x

= -3x²-2x² +12x-6x

= -5x² +6x

Hence, the equivalent expression is equal to -5x² +6x.

The scale drawing of a porch is 8 inches wide by 12 inches long. If the actual porch is 12 feet wide, what is the length of the porch?

Answers

Answer:

The actual length of the porch is 18 feet.

Explanation:

Scale = [tex]\frac{length on drawing}{actual length}[/tex]

So that considering the width of the drawing and actual porch,

1 foot = 12 inches

12 feet = 12 x 12 inches

           = 144 inches

scale = [tex]\frac{8}{144}[/tex]

         = [tex]\frac{1}{18}[/tex]

Given that the length of the porch drawn is 12 inches, let the actual length of the porch be represented by x. Then the actual length can be determined by;

scale = [tex]\frac{length on drawing}{actual length}[/tex]

[tex]\frac{1}{18}[/tex] = [tex]\frac{12}{x}[/tex]

x = 12 x 18

  = 216

x = 216 inches

But,

1 foot = 12 inches

216 inches = 18 feet

The actual length of the porch is 18 feet.

Answer:

18ft
