Solve x2 = 144. 72 12 ±12 −12

Mathematics
1 answer:
Afina-wow [57]4 years ago
6 0

If x²=144, then x= positive 12 and x= negative 12.

I have no idea what the '72' is doing in there.
If it means  x²=144.72 , then

     x = +/- 12.03 (rounded)

Oh wait.  Now I understand what the 72 is.  It's one of the answer choices.
Specifically, it's the customary absurd choice for students who have no clue.

there are 6 flavors of candy in a bag strawberry lime lemon cherry or grape what is the probabilty of selecting blueberry
Furkat [3]

Number of strawberry = 1

Number of Lime = 1

Number of Lemon = 1

Number of Cherry = 1

Number of Blueberry = 1

Total number of candies = 1 +1 + 1 +1 +1 +1 =6

favourable outcome = 1

P(of selecting blueberry ) = \frac{Number of Blueberry }{Total number of candies}

P(of selecting blueberry) = \frac{1}{6}

P(of selecting blueberry) = 0.1666

P(of selecting blueberry) = 0.17

Andy drove 840 miles in 12 hours. How far could he drive in 3 hours?​
liraira [26]
To answer this, we need to first find the rate and the multiply it by 3. 840/12 = 70 miles per hour. Then multiply it by 3. 70*3=210 miles. Another way we can do it is that we can divide 840 by 4 because 12 hours / 4 = 3 hours. 840/4 = 210 miles.
