So one way we can do this is-
2(2n+7)+3n=
4n+14+3n=
7n+14
Another simpler way possible is-
2n+7+2n+7+3n=
RE-ORDER
2n+2n+3n+7+7=
COMBINE LIKE TERMS
7n+14
Answer:
12
Step-by-step explanation:
2*6=12
Consider a<span> right triangle with </span><span>hypotenuse of 1.
sin x means to divide the side in front of the angle by </span>hypotenuse<span>
cos x means to divide the side beside the angle by hypotenuse
we know that a^2+b^2=c^2 now divide two sides by c^2
c is 1 also a/c means sinx and b/c is cos x so
sin^2(x)+cos^2(x)=1
