working ;
(3x+2)^2
*Apply Perfect Square Formula : (a+b) =a^2+2ab+b^2
a = 3x,b = 2
(3x)^2 + 3x.2+2^2
finally Answer is:
= 9x^2 + 12x +4

Answer:
83.73 in³
Step-by-step explanation:
It is appropriate to use the formula for the volume of a cone:
V = (1/3)πr²h
V = (1/3)(3.14)(4 in)²(5 in) ≈ 83.73 in³
The volume of the cone is about 83.73 in³.

Answer:
The line with be duchess with shading below.
None of the above
Step-by-step explanation:
The correct inequality expression is;
y < 2x+3
Note that the inequality sign between the expressions is the one that will determine the nature of the line.
Since the sign is not containing the "equal to" sign this means that the line will be broken(duchess).
Since it is "less than", the shading will be below the line.
