Answer:

The answer is 2c + 7d.

Step-by-step Explanation:

(10c² + 49cd + 49d²) ÷ (5c + 7d)

  • = (10c² + 49cd + 49d²) \times  \frac{1}{5c + 7d}
  • =\frac{10c² + 49cd + 49d²}{5c + 7d}
  • = 2c + 7d

Hope it helps you! \(^ᴥ^)/

Which expression is not equivalent<br> to (x + 4)(x – 3)?
Digiron [165]

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

{x }^{2}  - 3x + 4(x - 3)

2) Expand by distributing terms.

{x}^{2}  - 3x + 4x - 12

3) Collect like terms.

{x}^{2}  + ( - 3x + 4x) - 12

4) Simplify.

{x}^{2}  + x - 12

<em><u>The</u></em><em><u> </u></em><em><u>second</u></em><em><u> </u></em><em><u>equation</u></em><em><u> </u></em><em><u>are</u></em><em><u> </u></em><em><u>equivalent</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>equation</u></em><em><u>.</u></em><em><u> </u></em><em><u>but</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>first</u></em><em><u> </u></em><em><u>equation</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>not</u></em><em><u> </u></em><em><u>equivalent</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>m</u></em><em><u>a</u></em><em><u>i</u></em><em><u>n</u></em><em><u> </u></em><em><u>equation</u></em><em><u>.</u></em>

I have 3 countries (Germany, usa, China) with 3 statistics (people per square km, internet users per 100 people, cell phone owne
kolbaska11 [484]
Alright, so if we wanted to take, for example, cell phone owners per 100 people and compare Germany to the USA, we can start by making up a number for Germany - 80 - and a number for the USA - 70. Next, the ratio of people using cell phones is 80/70=8/7 with the numerator being the people from Germany and the denominator being the number from the USA.

Which number produces an irrational number when multiplied by 1/2
Ludmilka [50]

Quick answer

Any irrational number. I can't think of any exception to this statement.

sqrt(5) is irrational.  1/2 * sqrt(5) is still irrational.

-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational

2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.

1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.

Conclusion

There are no exceptions to this.  All irrational numbers produce irrationals when multiplied by 1/2
