Answer:
where is the qwestion ,??
A) 3/4 is equal to 0.75. 1/2 is equal to 0.5. You need to find out how many parts of the grape juice you have. So you take your 9 quarts and divide it by 0.75. That equals 12. So for the 9 quarts you need, you will add 12 parts of the 3/4. Now you need to add 12 1/2s as well. So 1/2 (or 0.5) multiplied by 12 is 6. So your answer would be 6 quarts
x² - 14x + 46 = 0
subtract 46 from both-side
x² - 14x = -46
Add the square of the half of the co-efficient of x
x² - 14x + (-7)² = -46 + 7²
(x-7)² = -46 + 49
(x-7)² =3
Take the square root of both-side
x-7 = ±√3
x-7= ±1.732
Add 7 to both-side of the equation.
x= 7 ± 1.732
Eithe x= 7 + 1.732 or x= 7 - 1.732
x=8.732 or x=5.268
Therefore x = 8.732 , 5.268
Answer: C
I Hope this was Correct...
if not IM SUPER SORRY!
have an Blessed day
