Answer:
+5
Step-by-step explanation:
You add five to -7 you get -2 add five to -2 you get 3 and so on.
EXAMPLE
Find the distance between the points A(−4, −3) and B(5, 7).
SOLUTION
In this case, x1 = −4, x2 = 5, y1 = −3 and y2 = 7.
AB2 = (x2 − x1)2 + (y2 − y1)2
= (5 − (−4))2 + (7 − (−3))2
= 92 + 102
= 181
Thus, AB =
Note that we could have chosen x1 = 5, x2 = −4, y1 = 7 and y2 = −3 and still obtained the same result. As long as (x1, y1) refers to one point and (x2, y2) the other point, it does not matter which one is which.

Answer:
A) 3
Step-by-step explanation:
The notation f(x)=[x] represents the greatest integer function, with the integer being less than or equal to x.
Since we have to find the nearest integer smaller than the given number, we can say that greatest integer function always rounds down its input to the nearest integer.
We have to find the value of [3.6]. So we have to round down 3.6 to its nearest integer, which will be 3.
Therefore, the option A gives the correct answer.
Answer:
Height of the triangular face of the box is 12 cm.
Step-by-step explanation:
This question is not complete; please find the question as the attachment.
Volume of a triangular prism = Area of the triangular base × height
It's given in the question, Volume of the prism = 3240 cm³
Height of the prism = 30 cm
By substituting these values in the formula,
3240 = B × 30
B = 
B = 108 cm²
Area of the triangular face (B) = 
108 = 
108 = 9h
h = 12 cm
Therefore, height of the triangular face of the prism is 12 cm.
