I Need Help PLease!Ashton estimates the square root of 72 in the following way:
√72=
2√36=
2×6=12
Explain why his reasoning is incorrect.
Estimate the square root of 72 to the nearest tenth without using your calculator. Show your work.
Answer:

Answers

Answer:

\sqrt {72} = 6\sqrt 2

Step-by-step explanation:

Ashton estimates the square root of 72 in the following way:

√72=

2√36=

2×6=12

a) Explain why his reasoning is incorrect

This is incorrect because \sqrt2 * 6 is the correct answer but he has missed the square root term on 2.

=\sqrt {2^2X2X3^2 }

=\sqrt {2^2} \sqrt 2 \sqrt {3^2 }

=2 X \sqrt 2 X 3

= \sqrt 2 X 6

or can be written as:

= 6\sqrt 2

b) Estimate the square root of 72 to the nearest tenth without using your calculator. Show your work.

Find the factors of 72 we get \sqrt {2X2X2X3X3 }  

Now, we will combine 2 terms if the are same so,

=\sqrt {2^2X2X3^2 }

=\sqrt {2^2} \sqrt 2 \sqrt {3^2 }

=2 X \sqrt 2 X 3

= \sqrt 2 X 6

= 6\sqrt 2

\sqrt {72} = 6\sqrt 2

1/4 (8× - 4) = 5x + 8​

Answers

Answer:

x = -3

Step-by-step explanation:

What you do is get x by itself.

1/4(8x - 4) = 5x + 8 Distribute 1/4 to 8x and -4.

2x - 1 = 5x + 8 Subtract 5x on both sides.

-3x -1 = 8 Add -1 to both sides.

-3x = 9 Divide -3 on both sides.

x = -3

Answer: - 3

Step-by-step explanation:

Expand the brackets

It will give: 2x - 1 = 5x + 8

Collect like terms: 2x - 5x = 1 + 8

- 3x = 9

Divide both sides by - 3

x = -3
