The value of c, the constant of the function y = ax² + bx + c, exists -3.
<h3>What is an equation?</h3>
An equation exists as an expression that indicates the relationship between two or more numbers and variables.
Given that: y = ax² + bx + c
At point (4, 21)
21 = a(4²) + 4b + c .......(1)
At point (5, 32)
32 = a(5²) + 5b + c .........(2)
At points (6, 45)
45 = a(6²) + 6b + c .......(3)
Therefore, the value of a = 1, b = 2 and c = -3.
The value of c, the constant of the function y = ax² + bx + c, exists -3.

The side length is 3 inches
<h3>What is the perimeter of a cube?</h3>
The formula for perimeter of a cube is given as:
Perimeter = 12 × side length
We have that;
- Perimeter = 36 inches
- Side length be x
Substitute into the formula
12x = 36
Divide both sides by 12
12x/12 = 36 / 12
x = 3 inches
The side length is x and equal to 3 inches.
Hence, the side length is 3 inches
