Step-by-step explanation:
Answer:
17) 26
18) 66
19) 78
20) 145
Step-by-step explanation:
#17) 8 + 3n for n = 6
8 + 3*(6)
8 + 18 = 26
#18) (8 + 3)n for n = 6
(8 + 3)*6
(11)*6 = 66
#19) 90 - 4d for d = 3
90 - 4*(3)
90 - 12 = 78
#20) 7x + 2y for x = 15, y = 20
7*(15) + 2*(20) = 145
Answer:
the polynomial has degree 8
Step-by-step explanation:
Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.
So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.
1) term 
contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6
2) term 
contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7
3) term 
contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8
This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
What we know: Lucy's snake eat's 2 mice a week.
To find the answer, you'll have to multiply 2 by 6.
So, since Lucy's snake eats 2 mice a week for 6 weeks.
To find the amount of mice her snake has eaten in the past 6 weeks you'll have to multiply 2 and 6.
2x6=?
------------------------------------------------------------------
The first week the snake ate 2 mice.
The second week the snake ate 2 mice.
The third week the snake ate 2 mice.
The fourth week the snake ate 2 mice.
The fifth week the snake ate 2 mice.
The sixth week the snake ate 2 mice.
Your answer would be: 12
