Answer:
x = ±2
Step-by-step explanation:
3x ^2 -4 = 8
Add 4 to each side
3x ^2 -4+4 = 8+4
3x^2 =12
Divide each side by 3
3x^2 =12
3x^2/3 = 12/3
x^2 = 4
Take the square root of each side
sqrt(x^2) = ±sqrt(4)
x = ±2
Answer:
Cooper made $22.80 per hour.
Step-by-step explanation:
Since Cooper made a total of $228.00 within 10 hours, the money he made each hour is equivalent to the rate of change. That means that in order to get the amount of money made in one hour, you must first turn the ten hours into one using division. Since you divided ten into one using division, you divide the $228.00 by ten using division.
228 divided by 10 is 22.8, therefore Cooper is making $22.80 per hour.
Answer:
42 ft, 60 ft, 84 ft
Step-by-step explanation:
let x be the shortest side , then the other 2 sides are 2x and x + 18, so
x + 2x + x + 18 = 186 , that is
4x + 18 = 186 ( subtract 18 from both sides )
4x = 168 ( divide both sides by 4 )
x = 42
Then lengths of sides are
x = 42 ft
2x = 2 × 42 = 84 ft
x + 18 = 42 + 18 = 60 ft
