Here, y is a cubic function of x.
When x = 3,



Hence, when x = 3, y = 126.
Sec θ = 3
1/cos θ = 3
1/sin(90 - θ) = 3
csc(90 - θ) = 3
I'm pretty sure the answer would be 2.
Sorry if it's wrong
Answer:
The perimeter of the shape is (7x²+10x+81) inches.
Step-by-step explanation:
When finding the perimeter of a shape, you have to add up all the side lengths :



x + y = -9
x + 2y = -25
Rewrite the first equation as x = -9-y
Relace x in the second equation:
-9-y + 2y = -25
Simplify:
-9 +y = -25
Add 9 to both sides:
y = -16
Now you know y,, replace y in the first equation and solve for x:
x -16 = -9
Add 16 to both sides:
x = 7
Answer: x = 7
