You have 22+3x/3x+7=2. That 3x/3x raises eyebrows; is this what you meant, with the result that 3x/3x = 1? or did you mean
3x
22 + ------------- + 7 = 2?
3x+7
If you meant the latter, then simplify the equation by subtracting 2 from both sides:
3x
27 + ---------- = 0
3x+7
Multiply all three terms by (3x+7), obtaining
27(3x+7) + 3x = 0
Then 21x + 3x + 189 = 0, so that 24x = -189, or x = -189/24 = -7 7/8
Just subtract each term from the next term.
So:
2nd term minus 1st term = 0.26 - 0.36 = -0.1
3rd term minus 2nd term = 0.16 - 0.26 = -0.1
etc
So common difference is -0.1
Answer:
x = - 2 ±
Step-by-step explanation:
Given
x² = - 4x + 3 ( add 4x to both sides )
x² + 4x = 3
To complete the square
add (half the coefficient of the x- term)² to both sides
x² + 2(2)x + 2² = 3 + 2²
(x + 2)² = 3 + 4 = 7 ← take the square root of both sides
x + 2 = ± ← subtract 2 from both sides
x = - 2 ± ← exact values

hopefully its right i'm not good at this kind of stiff
You know that
1 yard = 36 inches.
Moreover,
1 square yard =1 yard × 1 yard
Then
1 square yard = 36 inches × 36 inches = 1,296 square inches.
Answer: correct choice is C.
