Answer:
15 lb
Step-by-step explanation:
let the current weight of the puppy be X, the initial weight of the puppy is 4lb or 
, (6 lb less 2/3 X) .
#We equate the current weight to the initial weight to determine X:
Hence, the current weight of the puppy is 15 lb
Here you go!! It's always best to graph these questions, if you have graph paper near.
If not there are online graphing websites to use!! :))
ANSWER: Choice D (4th answer)
If the shaded region is the area inside the rectangle but outside the square, then the area is 121-25pi or 42.4602
The identity in question is
cos(a - b) = cos(a) cos(b) + sin(a) sin(b)
so that
cos(a - b) = 12/37 cos(a) + 3/5 sin(b)
Since both a and b lie in the first quadrant, both cos(a) and sin(b) will be positive. Then it follows from the Pythagorean identity,
cos²(x) + sin²(x) = 1,
that
cos(a) = √(1 - sin²(a)) = 4/5
and
sin(b) = √(1 - cos²(b)) = 35/37
So,
cos(a - b) = 12/37 • 4/5 + 3/5 • 35/37 = 153/185
3terms = trinomial (7a^2, 4a, -12)
Degree of each term 2nd, 1st, constant
Largest degree: 2nd
