Answer:
2a^4 / b^5
Step-by-step explanation:
(2a^2 / b) x ( a / b^2) ^2
= (2a^2 / b) x (a^2 / b^4)
= 2a^4 / b^5
(p.s if you are not gonna do it don't say "no thanks" and leech off this poor man's points)
3x^2-12x+1=0
Use formula to solve quadratic eqns
Standard form of quadratic eq is ax^2+bx+c
-b(+,-)sqrtb^2-4ac/2a
Now can u find x?
The sound intensity of rustling leaves, y = 20 decibels
<u>Step-by-step explanation:</u>
y = 10logx
The sound intensity of rustling leaves is 100 times the reference intensity.
x = ratio of intensity of sound to reference to intensity
x = 100:1 or x = 100
y = 10 log(100) = 10 * 2 = 20 decibels
y = 20 decibels
If you factor the expression, your answer would look like this:
x + x^2 + 4
If you simplify the expression, your answer would look like this:
x^2 + x + 4
U = 2x - 2
We simply need to isolate x :) That just means that we need to get x onto it's own side of the equal sign.
So, add 2 to both sides.
2 + u = 2x
Then, divide both sides by 2.
2 + u ÷ 2 = 2x ÷ 2
Simplify.
1 + u/2 = x
So, x = 1/2u + 1
