Answer:
D. is your answer
Step-by-step explanation:
Answer: 0
Step-by-step explanation: each number divided by 0 is 0
Answer:
+ 
Step-by-step explanation:
To complete the square, with the coefficient of the x² term = 1
add ( half the coefficient of the x- term)² to both sides
x² + 3x + (
)² = 6 + ()²
x² + 3x + = 6 +
This is algebra disguised as geometry. I object. There are much better ways to combine algebra and geometry.
Anyway, in a parallelogram the diagonals meet at their midpoints, so bisect each other. So we have two pairs of congruent segments; geometry over.
3x + 1 = x+27
79 - y = 2y + 22
We can ignore the one about x.
79 - 22 = 2y + y
57 = 3y
y = 19
Answer: 19
<h3><u>
The value of x is equal to 21.</u></h3>
13 = 5 + 2(x - 17)
<em><u>Distributive property.</u></em>
13 = 5 + 2x - 34
<em><u>Add 34 to both sides.</u></em>
47 = 5 + 2x
<em><u>Subtract 5 from both sides.</u></em>
42 = 2x
<em><u>Divide both sides by 2.</u></em>
x = 21
