You first have to distribute the negative to the second pair of parenthesis. So the new equation would be 2n-4-4n+3. Next you combine like terms. So your final answer is -2n-1.
The answer would come out to be the last choice. Because the double lines in both D and R means they are congruent just like the single lines in S and E which also means they are congruent. The other angles all equal 90.
D. The graph of g(x) is the graph of f(x) shifted 8 units to the right.
Answer:x^2=2^2+4^2. x=4.47
Step-by-step explanation:
Opposite=m=2
Adjacent=n=4
Hypotenuse=x
x^2=m^2+n^2
x^2=2^2+4^2
x^2=4+16
x^2=20
x=√20
x=4.47
