The answer will mostly be true if you know the answers
Use the foil method to multiply out the expressions. Then solve for x by first combining like terms and then using inverse properties
Answer:
degree 4
Step-by-step explanation:
The degree of a polynomial is determined by the term with the largest exponent for the polynomial in standard form
Given
P(x) = (x - 1)(x + 2)(x + 3)(2x - 5)
We need only consider the product of the leading terms in each factor, that is
x(x)(x)(2x) = 2
← is the leading term in the expansion of the factors
with exponent 4
Thus polynomial is of degree 4
The answer is 1,2,4,6,8 because the circle has a circumference of 9
