You wrote it there yourself, at the beginning of your question.
You wrote E = I x R
Divide each side by ' I ' : E / I = R
That's what you're asking for. ^
Answer:
1.No, 143 is not a prime number. The list of all positive divisors the list of all integers that divide 143 is as follows: 1, 11, 13, 143. To be 143 a prime number, it would have been required that 143 has only two divisors, itself and 1.

Answer:
"simplify"
Step-by-step explanation:

Other possible simplification steps include combining fractions, reducing fractions, and rationalizing denominators (eliminating surds or complex numbers).
It appears the vocabulary word that is desired in the blank is <u>simplify</u>.
To me it sounds like 4 divided by n +5
