To be able to compete in a particular class, a bodybuilder can weigh in at no more than 175 pounds and no less than 145 pounds. If the clothes the wrestlers wear add 1
pound, what is the actual weight range, in pounds, for these bodybuilders (in interval
notation)?

B. [144, 174]

Step-by-step explanation:

Given

Total Weight Range = Not less than 145lb and Not more than 175lb

Required

Determine the actual weight range

Let x represent the total possible weight of a bodybuilder

From the question, we understand that the total weight is within the range of 145 to 175. i.e.

Also from the question, we understand that the bodybuilder's cloth adds 1 lb to the total weight;

The next step is to subtract this 1 lb from the range of total weight to get the actual weight range

This is as follows

This gives

From the list of given options, the correct answer is [144,174]

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
