Answer:</h2>
<u>The term that describe a fraction that has a polynomial in its numerator and its denominator is </u><u>Rational Expression</u>
<h2>Explanation:</h2>
The term that describes a fraction ,it has a variable or variable expression in its numerator, its denominator, or both is called a rational fraction. It is occur when both the numerator and the denominator are polynomials.In the below example xy are polynomials.
For example a rational expression given by 25x²y²/ 6xy can be simplified into (25 × x × x× y× y)/ 6× x× y
So
=25xy /6
Answer: 4
Step-by-step explanation: 4 was the biggest denominator in that equation. so if we multiply by 4 on all the terms, all the denominators will go away. we will not have any more fractions!
Those are supplementary angles, therefore:

Answer:
Total charge= -25
Step-by-step explanation:
Given :
Charges of some ions
Aluminium +3
Phosphate -3
Chloride -1
Silver +1
To find total charge on 8 phosphate,7 chloride and 2 Aluminium atoms
Aluminium +3 × 2 =+6
Phosphate -3 × 8 = -24
Chloride -1 × 7 = -7
total charge=
+6-24-7 =+6 -31
= -25
Answer:

Step-by-step explanation:
Given

=
×
← cancel (x + 50)(x + 1) on numerator/denominator
