Since 6 is positive, it's (x+blank)^2
6/2=3, and (x+3)^2 = x^2+6x+9. We have x^2+6x-2, so we have to add 9 to both sides to get (x+3)^2-2=9, then subtract 9 from both sides to get
(x+3)^2-11=0, or (x+3)^2=11. Square root both sides to get x+3=sqrt(11), and x=sqrt(11)-3, which is approximately 0.32

Answer:
x = 
Step-by-step explanation:
Given
x + 
+ (x - 1) = 
Multiply through by 10 ( the LCM of 2 and 5 ) to clear the fractions
10x + 15 + 10(x - 1) = 8
10x + 15 + 10x - 10 = 8
20x + 5 = 8 ( subtract 5 from both sides )
20x = 3 ( divide both sides by 20 )
x =
Answer:
The answer is A
Step-by-step explanation:
The domain is all the X values and the range is all the Y values. You do this when finding the domain and range of given pairs or a table.
Answer:
the number of branches required to use 25 wreaths is 75 branches
Step-by-step explanation:
Given that
The florist used 225 branches of winterberry for making 75 wreaths
First we have to compute the unit rate or the ratio
= 225 ÷ 75
= 3 : 1
Now the number of branches required to use 25 wreaths is
= 3 × 25
= 75 branches
Hence, the number of branches required to use 25 wreaths is 75 branches
