Answer:

3.4X10^-4

remove the zeros and add a decimal point after the first number eg.

<u>0.000</u>34 -->  34 --> 3.4

then add a x 10 eg.

3.4x10

then add a power- if the number is larger than 1 count the amount of zeros and add that as your power eg.

3400 -> 34 -> 3.4 -> 3.4x10^2

If the number is lower than one use a negative power eg.

0.00034 -> 34 -> 3.4 -> 3.4x10^-4

(Hope this helps sorry if its to complicated)

Lin has a drawing with an area of 20 in squared. If she increases all sides by a scale factor of 4, what will the new area be?
diamong [38]

The new area will be 320 in²

<em><u>Explanation</u></em>

Lin has a drawing with an area of 20 in² and she increases all sides by a scale factor of 4.

<u>The general rule</u> we need to use here.......

"<em>If the lengths of the sides in a shape are all increased by a scale  factor of  k, then the area will be increased by a scale factor of  k^2"</em>

Here the sides are increased by a scale factor of 4. So, the area will be increased by a scale factor of  (4)^2 =16

Thus, the new area will be:  (20*16)in^2 = 320in^2
