Answer:
(f-g)(x)= -2x
(f.g)(x)= 3x^2 + 8x +4
(f+g)(-1)=0
Explanation:
Given:
f(x) = x + 2
g(x) = 3x + 2
(f-g)(x)=?
(f.g)(x)=?
(f+g)(-1)=?
The expression for (f-g)(x) is:
(f(x)-g(x))(x) = (x + 2) - (3x + 2)
=x+2-3x-2
Simplify
(f(x)-g(x))(x) = -2x
The expression for (f.g)(x) is:
And, the evaluation for (f+g)(-1) is:
(f(x) +g(x))(-1) = ((x + 2)+(3x + 2))(-1)
This means we let x= -1.
We plug in what we know:
=x + 2+3x + 2)
=-1+2+3(-1)+2
Simplify:
=-1+2-3+2
=-4+4
(f(x) +g(x))(-1) = 0
Therefore:
So the rule for interior angles in a triangle, is that all interior angles add up to 180*.
With this information, you can do:
47 + 64 = 111
180-111= 69
So, in conclusion,
x = 69

I hope this helps you out!
Okay, ask yourself this : how many times does 6 goes into 30?
6 and 1 = 6
6 and 2 = 12
6 and 3 = 18
6 and 4 = 24
6 and 5 = 30
6 goes into 30 a number of 5 times. And so that means that :
60 and 1 make 60.
60 and 2 make 120
60 and 3 make 180.
60 and 4 make 240
60 and 5 make 300
FIVE (5) groups of 60 make 300.
Answer:
k=45
equation: y=x+45
Step-by-step explanation:
60=15+k
substract 15 on both sides to get 45=k
