The equations a = n, b = 2n + 6 and c = n² - 1 are polynomials, and the expression for ab - c is n² + 6n + 1
<h3>How to determine the expression for ab - c?</h3>
The polynomials are given as:
a = n
b = 2n + 6
c = n² - 1
The expression ab - c is calculated using:
ab - c = n * (2n + 6) - (n² - 1)
Expand
ab - c = 2n² + 6n - n² + 1
Collect like terms
ab - c = 2n² - n² + 6n + 1
Evaluate
ab - c = n² + 6n + 1
Hence, the expression for ab - c is n² + 6n + 1

Answer:
0.8
Step-by-step explanation:
I Dont know 3, 4, 5 so I am going to just use the normal formula
a^2 + b^2 = c^2
0.6^2 + b^2 = 1^2
0.36 + b^2 = 1
b^2 = 0.64
b= 0.8
V^2 = u^2 - 2as
v^2 + 2as = u^2
v + or - the square root of (2as) = u
** if it’s not this, then the answer is:
v + the square root of (2as)
