What is the answer A B C or D
2 answers:
We know that the box is a cube, so we know that this box has 6 sides of equal area.
So if one of the sides is 8.5 inches, then since it's a square, we know all of the sides are also 8.5 inches.
So the area of one side of the box is
Then we need to multiply this by 6 to get the total surface area of the box:
So now we know that the total surface area of the box is C) 433.5 square inches.

Answer:
Step-by-step explanation:
This is written in the standard form of a quadratic function:
where:
- ax² → quadratic term
- bx → linear term
- c → constant
You need to convert this to vertex form:
where:
- (h,k) → vertex
To find the vertex form, you need to find the vertex. For this, use the equation for axis of symmetry, since this line passes through the vertex:
Using your original equation, identify the a, b, and c terms:
Insert the known values into the equation:
Simplify. Two negatives make a positive:
X is equal to 3 (3,y). Insert the value of x into the standard form equation and solve for y:
Simplify using PEMDAS:
The value of y is -6 (3,-6). Insert these values into the vertex form:
Insert the value of a and simplify:
