So firstly, you want to foil - (7v^4 + 6) [Think of the minus sign as -1]:
Next, combine like terms and your answer will be:
You answer is a^10
when multiplying by exponents, you really add them
M = 3
passing thru <span>(2,3)
y = mx + b
3 = 3(2) + b
3 = 6 + b
so b = -3
equation : y = 3x - 3</span>
Answer:
The variance is
Step-by-step explanation:
From the question we are told that
The sample size is n = 21
The sum of squares is
Generally the variance is mathematically represented as
substituting values
