What does it want a unit rate? or?
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.

Answer:
90 * 40 = 3600 * $30 = $108,000
Step-by-step explanation:
He didn’t combine the -5r + 4r correctly and also he didn’t multiply 4 and -5 correctly.
if you can show your work. use
F O I L method
first
outer
inner
last.
r • r = r^2
r • -5 = -5r
r• 4 = 4r
4• -5 = -20.
the final equation is
R^2 + r -20
