Answer: the decimal should still be there but you don’t want to have a zero so 3.42 would be correcr
Step-by-step explanation:
<span>1. The area of a circle A found by using the formula pi(r^2) is an irrational number.
2. The number N of equal slices in a pizza; the portion P of the pizza in one slice is a rational number.
3. The air temperature T in Saint Paul,MN, measured to the nearest degree fahrenheit is an integer.</span>
Answer:
The reason why it is incorrect to cancel the 4x in the numerator with the 4x in the denominator is because 4x is not a factor of both the numerator and the denominator
Step-by-step explanation:
The denominator of the rational expression, x^2 + 4x - 12 given above is a quadratic equation. It is not factorizable. If we factorize the numerator, 4x - 8, we would have
4 (x - 2).
This means 4x is not a factor of the numerator(4x - 8) and neither is it a factor of the denominator (x^2 + 4x - 12). This is the reason why it is incorrect to cancel the 4x in the numerator with the 4x in the denominator. The factors of the denominator can only be gotten by using the general formula for solving quadratic equations
