Answer:

The correct answer is third option

(10x² - 4) - (7x² + 3)

Step-by-step explanation:

From the given option we get the correct answer is third option.

(10x² - 4) - (7x² + 3)

<u>Check the correct answer</u>

(10x² - 4) - (7x² + 3) = 10x² - 4 - 7x² - 3)

= 10x² - 7x² - 4 - 3 = 3x² - 7

Therefore the correct answer is third option

(10x² - 4) - (7x² + 3)

Answer:

4^2+2^2, 5^2, 6^2-6

Step-by-step explanation:

4 to the power of 2 is 16 and 2 to the power of 2 is 4. 16+4 is 20.

5 to the power of 2 is 25 which is greater than 20.

6 to the power of 2 is 36 minus 6 is 30 which is greater than 25 and 20.

Well 75x12=900 so 900 divided by 40 is 22.5 so 22 teachers can have 40 chalks but the principal needs to order another 20 :)

Isolate the variable to find the solution of the equation. 6. 2w = 18. 6 w = 3 w = 12. 4 w = 24. 8 w = 115. 32.

Anarel [89]

An equation is formed of two equal expressions. The solution of the equation is w=3.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

In order to solve the equation, we need to isolate the variable in the following manner, therefore, the solution of the equation can be written as,

$6.2w=18.6$

Divide both sides of the equation by 6.2,

$6.2w=18.6\\\\\dfrac{6.2w}{6.2}=\dfrac{18.6}{6.2}\\\\w = 3$

Hence, the solution of the equation is w=3.
