Answer:
4/6 and 6/15
Step-by-step explanation:
simplify all fractions to lowest possible.
4/6 = 2/3
10/25 = 2/5
6/15 = 2/3
4/6 and 6/15 are equivalent
Answer:
12
Step-by-step explanation:
Answer:
c(x)=(x+3)^2+5
Step-by-step explanation:
To complete the square, the same value needs to be added to both sides.
So, to complete the square x^2+6x+9=(x+3)^2 add 9 to the expression
C(x) =x^2 +6x + 9 + 14
Since 9 was added to the right-hand side also add 9 to the left-hand side
C(x) +9= x^2 +6x + 9 + 14
Using a^2 + 2ab + b^2=(a+b)^2, factor the expression
C(x)+9= (x+3)^2 +14
Move constant to the right-hand side and change its sign
C(x)=(x+3)^2 +14 - 9
Subtract the numbers
C(x)= (x+3)^2 +5
Any value of y, except when y = -4.9, will make the expression equal to 2.45.
