Answer:
All but the first answer choice could be the length and width of a rectangle.
Step-by-step explanation:
3 cm and 8 cm produce 24 cm^2 when multiplied together. Reject.
1 cm and 20 cm, when multiplied together, result in 20 cm^2. Select.
2 cm and 10 cm => 20 cm^2 Select
4 cm and 5 cm => 20 cm^2. Select
<span>Depending on the equation there can be three possible cases:
1- There can be 1 specific solution for the variable:
2x+4= 3
where x= -1/2
2- there can be an infinite amount of solutions:
2x+x-2=3x-3+1
where x=x
3- there can be no answer:
3+2x-x=5-3x+4x
where the solution doesn't exist</span>
I think using a computer software would be the best answer because it is then fair
If we convert the given in its mathematical form, we have,
(30x⁶/14y⁵)(7y²/6x⁴)
It can be observed that the numerator of the first and the denominator of the second have a common factor of 6x⁴. Also, the denominator of the first and the numerator of the second expression have a common factor of 7y².
((6x⁴)(5x²)/(7y²)(2y³))(7y²/6x⁴)
Cancellation of the common terms will give us an answer of,
<em>5x²/2y³
</em><em />Therefore, the simplified version of the involved operation is 5x²/2y³. <em>
</em>
The answer is A.All real numbers except -2.
