Answer:

- 5 < x < 31

Step-by-step explanation:

Inequalities of the type | x | < a, always have a solution of the form

- a < x < a

given | x - 13 | < 18, then

- 18 < x - 13 < 18 ( add 13 to all 3 intervals )

-5 < x < 31

Rewrite the inequality without the absolute value

-18 < x - 13 < 18

Add 13 to the whole equation

-18 + 13 < x < 18 + 13

Simplify

<u>-5 < x < 31</u>

3³+1x9+12 answer please, I really think it's 48.
UNO [17]

Answer:

You are correct the answer is 48.

Step-by-step explanation:

To begin solving this question you would want to start simplifying it to make it more understandable.

3^3 is 27 which now gives you 27 + 1 x 9 +12 which makes it easier to solve.

Then you would take 1 x 9 = 9 (multiply left to right)

Now it is simple addition

27 + 9 + 12 = 48

Hopefully this helps.

The length of a square is 10 cm. Calculate the perimeter of the square A. 40cm² B. 400cm² C. 4ocm D. 414cm² I will mark you as b
noname [10]

Answer:

C. 40 cm

Step-by-step explanation:

length of side of square = s

perimeter = s + s + s + s = 4s

We use the formula P = 4s

P = 4 * 10 cm

P = 40 cm

Answer: The perimeter is 40 cm.

Notice that the perimeter is a sum of lengths, so its units are linear units such as cm, inches, feet, a unit of length.

An area has square units such as cm^2, in.^2, ft^2, etc.

X - 4 = -4 - 4<br><br> 2 - 3x = -x - 8<br><br><br> Please help me solve these
irina [24]
X - 4 = -4 -4

Combine the two -4.

X - 4 = -8

Add 4 on both sides to isolate the x and get your answer.

X = -4

2 - 3x = -x - 8

Subtract the 2 on both sides.

-3x = -x - 10

Add the x on both sides.

-2x = -10

Divide by -2 on both sides to isolate the x and get your answer.

x = 5
