Answer:
The answer is 90 degrees. Have a good day!
Step-by-step explanation:
no they are different
if Base are equal power are added
like wise in first expressions power are added
but in second expressions cube of three is written as x to the power.
so they are not equal
![3(5x - 4) - (-30-45x)](https://tex.z-dn.net/?f=3%285x%20-%204%29%20-%20%28-30-45x%29)
![= 15x - 12 + 30 + 45x](https://tex.z-dn.net/?f=%3D%2015x%20-%2012%20%2B%2030%20%2B%2045x)
<- Distributive Property
![=60x + 18](https://tex.z-dn.net/?f=%3D60x%20%2B%2018)
<- Combine Like Terms
If you're trying to solve for 0:
![0 = 60 x + 18](https://tex.z-dn.net/?f=0%20%3D%2060%20x%20%2B%2018)
![-18 = 60x](https://tex.z-dn.net/?f=-18%20%3D%2060x)
<- Subtracted 18 from both sides
![x = \frac{-18}{60} = \frac{-9}{30}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-18%7D%7B60%7D%20%3D%20%5Cfrac%7B-9%7D%7B30%7D)
<- Divided both sides by 60 and then simplified.
![x = \frac{-9}{30}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-9%7D%7B30%7D)
<- Fraction Form
![x = -0.3](https://tex.z-dn.net/?f=x%20%3D%20-0.3)
<- Decimal Form
Give Brainliest for simple answer plz :P
13-9 = 4
4-4 = 0
0 divided by 2 = 0
2x = 0
x = 0
and h(x)= 2x-8
g o h is a composition function
First we find g o h
g o h is g(h(x))
We plug in h(x) in g(x)
We replace x with 2x-8 in g(x)
![g(h(x)) = g (2x-8) = \sqrt{2x-8-4} = \sqrt{2x-12}](https://tex.z-dn.net/?f=g%28h%28x%29%29%20%3D%20g%20%282x-8%29%20%3D%20%5Csqrt%7B2x-8-4%7D%20%3D%20%5Csqrt%7B2x-12%7D)
![g(h(x)) = \sqrt{2x-12}](https://tex.z-dn.net/?f=g%28h%28x%29%29%20%3D%20%5Csqrt%7B2x-12%7D)
To find domain we look at the domain of h(x) first
Domain of h(x) is set of all real numbers
now we look at the domain of g(h(x))
Negative number inside the square root is imaginary. so we ignore negative number inside the square root
So to find domain we set 2x - 12 >=0 and solve for x
2x - 12 >=0
add both sides by 12
2x >= 12
divide both sides by 2
x > = 6
