Answer:
<u>Step-by-step explanation:</u>
y = x + 2 x + y = 3
Solve using Substitution Method by replacing y with x + 2:
x + (x + 2) = 3
2x + 2 = 3
2x = 1
x =
Next, replace x with 1/2 in one of the original equations and solve for y:
y = x + 2
= + 2
=

Answer:
Step-by-step explanation:
The given expression is .
The technique that can be used to factor this polynomial is the difference of two squares.
We rewrite the two expressions as;
Recall that;
Answer : 12
Explanation :
In the first row of the table, we find that the -2 is the change, and in the third row -6 is the change.
Using this, we can find that the second row should have -4 subtracted from 16.
We know this because from looking at the changes from the first and second row, the differences multiply by two, as the rows increase. So -2 multiplied by 2 is -4, and 16 subtract 4 is 12.
