Solve for x over the real numbers:
-x^2 - 12 = -87
Add 12 to both sides:
-x^2 = -75
Multiply both sides by -1:
x^2 = 75
Take the square root of both sides:
Answer: x = 5 sqrt(3) or x = -5 sqrt(3) both Answers are correct
The correct answers are A and B.
Hope this helps!
Answer:
1000 gallons of tank
Step-by-step explanation:
Answer: 3.75 miles
Step-by-step explanation:
Divide 30 by 8. 30/8= 3.75. If she walked 1/8 then she walked 3.75 miles
It would all depend on the number and the factors they have.
For example:
A. What is the LCM of 4 and 8? As you can see, 8 is a multiple of 4 since 4×2=8
But 4 is NOT a multiple of 8 so that means 8 is the LCM.
B. What is the LCM of 3 and 6? As you can see, 6 is a multiple of both 3 and 6 but 3 is not a multiple of 6
Answer: So based off on what I showed you, the LCM of two numbers where one is the multiple of the other number is the multiple of the other number. In other words, the bigger of the two numbers
