So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9

wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2

then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x

-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15

Write 0.00000000018 in a scientific notation

Ugo [173]

Answer:

$1.8*10^{-10}$

Step-by-step explanation:

To find the number in scientific notation you want to find how many times you have to move the decimal to get the decimal to be right after the first non-zero number. If you move to the left the exponent is positive and if you move it to the right the exponent is negative. The answer would be $1.8*10^{-10}$ .
