(2+4)/(-2-d) = -2
6 = -2(-2-d)
6 = 4 + 2d
2 = 2d
1 = d
Answer:
csc (- 30)° = - 2
Step-by-step explanation:
Using the trigonometric relationship
csc x = 
and the exact value sin30° = 
sin(- 30)° = - sin30° = - , thus
csc (- 30)° = 
= - 2
I want to say A because 3 and 5 have 15 and 6:15 is sounds like a ratio and D is just 4/10

The Length of the rectangle is 18 unit.
<h3>
What is the Perimeter of a Rectangle?</h3>
Perimeter of rectangle = 2(length + width)
Given the following:
Let x represent the width of the rectangle
Width of the rectangle = x
Length of the rectangle = 4x + 6
Perimeter of rectangle = 42 units
Therefore, we would write the following equation to find x based on the formula for finding the perimeter of a rectangle:
2(4x + 6 + x) = 42
2(5x + 6) = 42
10x + 12 = 42
10x = 42 - 12
10x = 30
10x/10 = 30/10
x = 3
The width (x) = 3.
Length of the rectangle = 4(3) + 6
Length of the rectangle = 18 unit.
