Y² + 4y + 4 = 7
- 7 - 7
y² + 4y - 3 = 0
y = -(4) ± √((4)² - 4(1)(-3))
2(1)
y = -4 ± √(16 + 12)
2
y = -4 ± √(28)
2
y = -4 ± 2√(7)

y = -2 ± √(7)
y = -2 + √(7) U y = -2 - √(7)

Step-by-step explanation:
(-8 , 12) and (36 , -21)
Answer:
The expression of the given statement is 8 y - 2 = 6.
Step-by-step explanation:
Here, let the unknown number = y
Now, product of y and 8 = 8 times y = 8 y
Also, two less than the product = Product - 2
So, two less than the product of 8 and y = 8 y - 2
Now, this above expression is equivalent to 6.
⇒8 y - 2 = 6
Hence the expression of the given statement is 8 y - 2 = 6.
The common difference is B. 5 because the numbers are increasing by 5.
1/9
Find the common denominator, 1/3 can be multiplied to get to ninths. 1/3 is equivalent to 3/9, and so 4/9 minus 3/9 is 1/9.
