17. Because 7 plus 4 equals 11 and if you add 6 you get 17
Answer:
Step-by-step explanation:
We are to find the product of the given expression. Given the expression
(3xy - 1) (4xy + 2), th product is derives by simply opening up the bracket as shown below;
The expression 2(6x²y²+xy-1) gives the required product.
In proving using the law of cosines, you need to consider these two key elements. The first element is a^2 + b^2 - 2abcosC and the second one is cosine^2 theta + sin^2 theta is equal to 1. Law of Cosines is derived from the Pythagorean Theorem
Answer:
- 328
Explanation:
16*2-3(2*6+12)*5 = 32 - 3(12+12)*5 = 32-3*24*5 = 32-360 = - 328
