Step-by-step explanation:
Answer:
Given that:
Take LCM of x+y and x-y is,
then;
Using the identities rule:
Combine like terms;
Therefore, the answer is,
Answer:
We calculate g(-5); then f(g(-5));
g(-5) = (-5)^2 - 4 = 25 - 4 = 21;
f(g(-5)) = f(21) = 5 x 21 - 1 = 105 - 1 = 104;

Answer:
Step-by-step explanation:
Note that the base angle of an isosceles triangle is equal hence;
3x+2 = 5x-30
3x - 5x = -30-2
-2x = -32
x = -32/-2
x = 16
Hence one of the base angle = 3(16)+2 = 50degrees
The sum of angle in the triangle is 180, hence
50+50+y = 180
100 + y = 180
y = 80 degrees
Hence the third angle is 80 degrees
