What is the solution to –4|–2x + 6| = –24?x = 0x = 0 or x = –6x = 0 or x = 6no solution
Juliette [100K]

The correct answers are the x = 6 and x = 0.

In order to find this, we can follow the order of operations.

–4|–2x + 6| = –24

Divide by -4

|–2x + 6| = 6

Since it is now equal to a absolute value, we have to solve for the positive and negative versions of the final answer. Let's start with the positive.

-2x + 6 = 6

-2x = 0

x = 0

Now for the negative

-2x - 6 = -6

-2x = -12

x = 6

These would be your two answers.

Ice cream is best stores at 4 degree F with an allowance of 3 degree F. What is the best range to store ice cream?
zhuklara [117]

Answer:

1°F to 7°F  is the best range to store ice cream.

Step-by-step explanation:

The ideal storage temperature of ice cream = 4°F

The allowance in the temperature is 3°F

So, the range of the store = 4°F ±  3°F

Now, 4°F + 3°F  =  7°F

and    4°F -  3°F  =  1°F

Hence, 1°F to 7°F  is the best range to store ice cream.
