x = 4 or x= -4

Step-by-step explanation:

2x^2 − 11 = 21

Add 11 to each side

2x^2 − 11+11 = 21+11

2x^2 = 32

Divide by 2

2x^2 /2 = 32/2

x^2 = 16

Take the square root of each side

sqrt(x^2) = sqrt(16)

x = ± 4

x = 4 or x= -4

First, see how many parts in total (6+2=8) then divide 80 by 8 which is ten. you then know that each part must be 10 ounces so 2 parts becomes 20 ounces of grape juice and 6 parts becomes 60 ounces of water
