Phoenix [80]

Answer:

4

Step-by-step explanation:

If you increase the scale factor by 4, the sides become:

L= 2×4 = 8

W= 3×4 = 12

Now to find the new area:

<u>8 × 12</u> = 96cm^2

<u>So, a scale factor of </u><u>4</u> would give the rectangle a scale factor of <u>96</u>.

<u>Hope this helps and have a nice day!</u>

How do you simplify an Algebraic expression ?
NeTakaya

Answer:

You can solve one by... it's hard to explain So i'll just show you

Step-by-step explanation:

Here's an example,

2x+7=4+5x

First you subtract the variables on both sides (lower variable)

2x+7=4+5x

-2x       -2x

Which will leave you

7=4+3x

The subtract the whole number on each side (lower number)

7=4+3x

-4   -4

Which will leave you

3=+3x

Then you divide on both sides

3/3   3/3

which should leave you

x=1
