18.1 multiplying polynomial expressions by monomials
The act of Multiplying a polynomial by a monomial is an easy one. An example of this is given as Multiply x – y – z by -8x².
What are Polynomial Expressions?Polynomials are regarded as the sums of specific terms of a given form k⋅xⁿ. Here, the k stand for any number and n stand for a positive integer.
To Multiply x – y – z by -8x².
One has to first Multiply each term of the polynomial x – y – z by making use of the monomial -8x².
⟹ -8x² * (x – y – z)
= (-8x² * x) – (-8x² * y) – (-8x² * z)
Note that the * sign connote multiplication.

The element that would be the most effective at accepting electrons from another reagent is
Answer:
Matching the elements to the appropriate blanks as follows :
1) The element that would most effective at accepting electrons is ; CI
2) The element that would be the best insulator is ; Cl
3) The element best to form an ionic compound with sulfur is ; Rb
The acceptance of electrons by elements depends on the electronegativity of the element. from the options listed the element with the highest level of electronegativity is Cl ( chlorine ) therefore it the most effective at accepting electrons
Cl ( chlorine) is a non metal and non-metals are semi-conductors or insulators. therefore Cl would act as the best insulator when compared to other elements.
when metals react with non-metals they form an ionic compound. for sulfur the best metal to react with it is Rb ( soft silvery metal ) and the reaction of Rb and sulfur in hydrogen gas. results in Rb₂S₅
Hence we can conclude Matching the elements to the appropriate blanks as follows : The element that would most effective at accepting electrons is ; CI, The element that would be the best insulator is Cl ,The element best to form an ionic compound with sulfur is ; Rb

When making smart food choices, what question should be asked before deciding to eat at a restaurant?
Answer:
Are the available choices in my nutritional goals
Explanation:
Smart food decisions are required for maintaining your body healthy especially when your following a diet and have a goal.
You work every saturday from 9:00 a.m. to 5:00 p.m. find the measure of the angle generated by the hour hand of a clock during this time in both degrees and radians. compare this angle with the angle generated by the minute hand from 9:00 a.m. to 5:00 p.m.
The angle generated by the hour hand measures -270° or -4.71 radians, and we will see that the angle generated by the minute hand is 12 times the one generated by the hour hand.
How to get the angle generated?Remember that in a complete rotation we have an angle of 360°, and in a complete rotation we have 12 hours, then there is a relation:
12 hours = 360°
1 hour = 360°/12 = 30°
From 9:00 a.m to 5:00 p.m. there are 9 hours, so the angle that the hour hand does is:
A = 9*(30°) = -270°
(the negative sign is because this angle is measured clockwise)
Now we can write this in radians, remember that:
3.14 radians = 180°
Then:
1 = (3.14 rad/180°)
Then:
270° = -270°*(3.14 rad/180°) = -4.71 rad
What is the angle generated by the minute hand?Each hour that passes, the minute hand does a complete revolution. Then in 9 hours, the minute hand does an angle of:
A = 9*(-360°) = -3,240°
To compare this angle to the one generated by the minute hand we take the quotient:
-3,240°/-270° = 12
So this angle generated by the minute hand is 12 times the one generated by the hour hand.
