Answer:
21x + 35y
Step-by-step explanation:
Distribute the 7 to everything in the parentheses.
7*3=21
7*5=35
Answer:
substitute that value for x in the polynomial and see if it evaluates to zero
Step-by-step explanation:
A "zero" of a polynomial is a value of the polynomial's variable that make the expression become zero when it is evaluated. As an almost trivial example, consider the polynomial x-3. The value x = 3 is a zero because substituting that value for x makes the expression evaluate as zero.
3 -3 = 0
___
Evaluating polynomials can be done different ways. Straight substitution for the variable is one way. Using synthetic division by x-a (where "a" is the value of interest) is another way. This latter method is completely equivalent to rewriting the polynomial to Horner form for evaluation.

Answer:
the probability that the ext order will be shrimp = 27.78%
Step-by-step explanation:
Vegetable 333
Chicken 666
Pork 222
Beef 222
Shrimp 555
total = 1,998
P (shrimp) = 555 / 1,998 = 0.2777 or 27.78%
in case the numbers in the orders were:
Vegetable 3
Chicken 6
Pork 2
Beef 2
Shrimp 5
total = 18
P (shrimp) = 5 / 18 = 0.2777 or 27.78%
The probability of an event happening is just the number of times that event occurred divided by the total number of events that took place.
