How do you do this? need it by tonight

Substitute "E" For X

First step:
When you divide, you subtract the exponents.
So first divide 9/3=3

**Then the smallest exponent number will be subtracted by the biggest exponent number. So x to the power of 2 subtract by x (when a variable is alone with no exponent, that means the exponent is 1).

Second step:
x to the power of 2 subtracted by x gives x, because 2-1 is 1 so you just put x.

Third step:
In division, + divided with - gives you a negative(-) answer.

Fourth step:
4/2 = 2

So the final answer is:
3x-2

Hope this helped!

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
