Answer:
Hi there!
The correct answer to this question is: 97/15
Step-by-step explanation:
First step is to change all the mixed fractions into improper fraction.
9 8/9 becomes 99/9 and 4 8/15 becomes 68/15
then you divide 99/9 you get 11. then you multiply 11 with 15 to get a common denominator. so now the equation is 165/15 - 68/15 which equals 97/15
A. because divide both side by -5 and reverse the sign because you divided
The answer: "4x² (x − 3)(x − 3)" ; or, write as: "4x² (x − 3)² " .

Given: " 4x⁴ − 24x³ + 36x² " ; The least common factor is: 4x² ;
since the least common NUMBER as a factor is "4"; and the least common "variable" as a factor is "x² " ;
_____________________________
4x⁴ − 24x³ + 36x² = 4x² (x² − 6x + 9) ;
Factor the: "(x² − 6x + 9)" ;
(x² − 6x + 9) = (x − 3)(x − 3) ;
Rewrite: "4x² (x − 3)(x − 3)" ; or, write as: "4x² (x − 3)² " .

A. Eli's error was 3900-3867=33 kg.
B. A fairly small child would weigh about 33 kilograms.
C. Macy's percent error was .7/70=.01, or 1%. Eli's was 33/3900.0085, or .85%. Macy's percent error was larger, so Eli is more accurate.
