Answer:
42
Step-by-step explanation:
j(5+k) + 15
Let j = 3 and k = 4
3(5+4) + 15
Parentheses first
3 (9) +15
Multiply
27 + 15
Add
42
We have the expression . To write a equivalent expression, we are going to rewrite the denominator of our expression using its common denominator 4:
Now, notice that we are basically diving 1 by , so we have a division involving fractions, and remember that to divide fractions, we just need to invert the second fraction and multiply:
We can conclude that the equivalent expression of is .
(this is not my answer but someone elses who answered the same problem on here)
For this case we must find the product of 
By definition, the distributive property states that:
Then, according to the expression we have:
Answer:
Option C
Answer:
I think the 3rd option but im not sure
Answer and Step-by-step explanation:
These two terms (pronounced as Sine and Cosine) are used to solve for the sides and angles of a triangle in Trigonometry.
They are functions revealing the shape of a right triangle.
Sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.
Cosine is also a trigonometric function of an angle. The cosine of an angle is the relation of the length of the side that is adjacent that angle, to the length of the longest side of the triangle.
