(f+g)(x)=0
f (x) + g (x)=0
now, 
substitute their values 
x^2 -4x + x -18 = 0
x^2 -3x -18 =0
x^2 - 6x + 3x - 18 =0
x (x-6) + 3 (x-6) = 0
(x-6)(x+3) = 0
we have to find it's zeroes (or roots) now:
x-6 =0
x = 6
x +3 =0
x = -3
        
             
        
        
        
The bases are both 2, so we would subtract the exponents. This is because the rule is
(a^b)/(a^c) = a^(b-c)
In this case,
a = 2
b = 3/4
c = 1/2
So this means
b - c = (3/4) - (1/2) = (3/4) - (2/4) = 1/4
After subtracting the exponents, the final exponent is 1/4
So the expression simplifies to 2^(1/4) which is the same as 
![\sqrt[4]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%7D)
 (fourth root of 2)
 
        
        
        
Answer:
angle 1 = 105º
angle 2  = 75º
Step-by-step explanation:
angle 2  = 75º
corresponding angle to the 75º angle
angle 1 = 105º
it's supplementary to angle 2
180 - 75 = 105
 
        
             
        
        
        
Answer:
8%
Step-by-step explanation:
$30 divided by 100= 0.3/1%
0.3x8=$2.40
$30+$2.4=32.40
