Answer:
x = 26, 16
Step-by-step explanation:
( x-21) ^2 = 25
Take the square root of each side
sqrt(( x-21) ^2) = ±sqrt(25)
x-21 = ±5
Add 21 to each side
x-21+21 = 21±5
x = 21±5
x = 21+5 and x = 21-5
x = 26, 16
Answer:1, 3, and 4
Step-by-step explanation: I just did it
0.6y=10.3 divide both sides by 0.6
y=10.3/0.6 which is an endless decimal so we should keep this in fractional form, multiply both sides by 10
y=103/6 or as a mixed fraction
y=17 1/6
