Answer:
A
Step-by-step explanation:
Given 2 sides and the included angle use the Cosine rule to solve for x
x² = 1.6² + 1.1² - (2 × 1.6 × 1.1 × cos78° )
= 2.56 + 1.21 - ( 3.52 × cos78° )
= 3.77 - 0.7318
= 3.0382
Take the square root of both sides
x = 
= 1.7 → A
It would be 12+n=4n
The sum (+) of 12 and a number (n) is (=) 4 times a number (4n)
The answer is the second option.
Calculate the square root which is -7*6-(-2)*(-3) and then multiply the numbers which is -42+2*(-3) that equals -42-6 and your answer is -48

Answer:
Option B
Step-by-step explanation:
The cost of 6 turkeys at $1 per pound will be between $78 and $90. The cost of 6 turkeys at $20 each, B2G1, will be $80. We imagine that the average weight of turkeys in the 13-15 lb range will usually exceed 13 1/3 pounds, the weight at which the cost per pound is the same. That means, 6 turkeys at $1 per pound will likely cost more than $80, unless extreme effort is made to choose only the lightest turkeys.
Option B is likely to be cheaper; certainly so, if heavier turkeys are preferred.
