Answer:
A=4.
Step-by-step explanation:
Note: In the expression of area the first term should be 
.
It is given that area of a rectangular floor of your house is 
and the length is 
units.
We know that, area of a rectangle is
Since length of the rectangle is , therefore is a factor of and the value of is 0 at x=-2.
Divide both sides by 4.
Therefore, the value of A is 4.
Cos²(x) + sin²(x)
¹/₂[1 - cos(2x)] + ¹/₂[1 + cos(2x)]
[¹/₂ - ¹/₂cos(2x)] + [¹/₂ + ¹/₂cos(2x)]
¹/₂ + ¹/₂ - ¹/₂cos(2x) + ¹/₂cos(2x)

Answer: 11, 7
11 + 7 = 18
11 x 7 = 77
Answer:
In Grade 8, 17% of students liked running
Step-by-step explanation:
Although this table is incomplete, there are still enough information to answer.
First, we need to be aware that the data here is written in decimal numbers, which is another way to write percentages.
In other words, 100% equals to 1, which is to say that if we multiply decimal number with 100 we'll get the percentage:
0.39 = 39%
0.04 = 4%
Another important thing to establish is that the value of decimal number DOES NOT mean the number of people, it only suggests the ratio:
0.26 does not mean 26 people etc.
Knowing this, from this incomplete table, we see that 0.17 students from grade 8 liked running. And now we know that 0.17 equals to 17%, which makes B the correct answer.
