Answer:

  • \boxed{\sf{4}}

Step-by-step explanation:

Use the order of operations to solve this problem.

\Longrightarrow: \sf{\sqrt{28-3(4)} }

<u>Remove parentheses.</u>

→ (4)=4

<u>Rewrite the problem down.</u>

\Longrightarrow:\sf{\sqrt{28-3*4} }

<u>PEMDAS stands for:</u>

  • <u>Parentheses</u>
  • <u>Exponents</u>
  • <u>Multiply</u>
  • <u>Divide</u>
  • <u>Add</u>
  • <u>Subtract</u>

→ 28-3*4

<u>Multiply.</u>

→ 3*4=12

→ 28-12

<u>Subtract.</u>

→ 28-12=16

\Longrightarrow:\sf{\sqrt{16} }

\Longrightarrow\sf{\sqrt{16}=4^2 }

<u>Use the radical rule.</u>

\Longrightarrow: \sf{4^2=\boxed{\sf{4}}

  • <u>Therefore, the correct answer is 4.</u>

I hope this helps you! Let me know if my answer is wrong or not.

The store sold 482 cameras in the month of March.

An equation is an expression that shows the relationship between two or more variables and numbers.

Assuming that the same number of camera is sold each month. Let x represent the amount of camera sold in March.

Since the electronics store sold 1,446 cameras in the first 3 months, hence:

3x = 1446

x = 482 cameras

The store sold 482 cameras in the month of March.

What is the pattern 324,256,196,144
Blababa [14]

The pattern of 324, 256, 196, 144 is the square of the even numbers in a descending order starting from 18.

<h3>What is a sequence?</h3>

A sequence is a set of things next to each other in a set order. It is also referred to as a series.

According to this question, the following sequence is given: 324, 256, 196, 144. A careful observation of these numbers shows that each is the square of even numbers.

18² = 324

16² = 256

14² = 196

12² = 144

Therefore, the pattern of 324, 256, 196, 144 is the square of the even numbers in a descending order starting from 18.
