Find the difference. 9 3x − 4 2x2

1 answer:

4 0

We are tasked to determine the difference between the two expressions such as 9+3x and 4+2x². In order for us to solve this, we need to arrange the terms in descending order such as shown below:
(3x + 9) and 2x² + 4
Then, we need to perform subtraction in the same terms only such as 9 and 4:
3x +9 - (2x² + 4)
3x + 9 -2x² - 4
3x + 5 - 2x²
Then arrange in descending order such as:
2x² + 3x + 5

The answer is 2x²+3x+5.

Answer:

Front: 33 ft

Back: 66 ft

Step-by-step explanation:

Let w be the width of the front yard

½[w + 2w]×2w = 3300

3w² = 3300

w² = 1100

w = 33.1662479036

w = 33 ft

2w = 66 ft

10. A weight hangs on a spring. The vibration period of that weight is the time in which it makes a complete cycle in motion. Su

Alenkinab [10]

The vibration period of the spring will be 0.2 seconds

Explanation

The relationship between the vibration period "T" (in seconds) and the weight "w" (in kilograms) is given by...

$T= 2\sqrt{\frac{w}{200}}$

Given that, the weight(w) = 2.0 kilograms

So, plugging w = 2.0 into the above equation, we will get...

$T= 2\sqrt{\frac{2.0}{200} } \\ \\ T= 2\sqrt{\frac{1}{100} }\\ \\ T= 2*\frac{1}{10}\\ \\ T= \frac{1}{5}=0.2$

So, the vibration period of the spring will be 0.2 seconds.

Answer:

Step-by-step explanation:

Decompose each number:

$6) 90 = 9 \times 10\\\\7) 40 = 4 \times 10\\\\8)890 = 89 \times 10\\\\9) 300 = 3 \times 100\\\\10) 7000 = 7 \times 1000\\\\11)3700 = 37 \times 100\\\\$

Correct the error. Write the correct decomposition:

$12) 560 = 56 \times 10\\\\13) 4300 = 43 \times 100\\\\14) 6000 = 60 \times 100 \ \ or \ \ 6 \times 1000$
