Answer:
y = -2x - 2
Step-by-step explanation:
The perp line is simply taking the negative reciprocal of the slope.
In this cale if +1/2 is the slope of the line, the flip it to get 2/1 which is just 2. Then multiply it by a negative.

______
Answer:
V < 5
V∈]-∞,5[
___________________
Step-by-step explanation:
V + 9 < 14 ⇔ V < 14 - 9 ⇔ V < 5.

Easy, showing work,
using the method FOIL (First,Outer,Inner, Last)
Take, (x+3)(x+5) and multiply,
First,
x*x=

Outer,
x*5=5x
Inner,
3*x=3x
Last,
3*5=15
Add the terms together,

+8x+15 (

+5x+3x+15)
Thus, your answer.
The surface area of the box is being referred to as A
The surface area will be the sum of the four rectangular sides' areas and the base area.
Base area = x²
Rectangular side area = xh
A = x² + 4xh
Volume is, as you said,
V = x²h
Lets substitute h from the formula of A to obtain A in our final answer. Substituting x is possible, but more difficult
(A - x²)/4x = h
V = (x²) * (A - x²)/4x
V = (Ax - x³)/4
