The sides in parentheses times 2 for each is equal to the perimeter expression.
Answer:
see below
Step-by-step explanation:
2x+8y=12 3x-8y=11
If we have to solve by substitution, Take the first equation and divide by 2
2x/2 + 8y/2 =12/2
x+4y = 6
Then subtract 4y from each side
x = 6 -4y
Then substitute this into the second equation
This is best solved by elimination
2x+8y=12
3x-8y=11
----------------
5x = 36
x = 36/5
Answer:
A. 31
Explanation:
The answer is A because a polynomial has at least two integers(more than two numbers) and A is just one integer, someone could get confused thinking is C but its not because <em>y³ </em>means <em>y×y×y, so that would not be the answer. </em>
