Step-by-step explanation:
you divide both sides by the right number
for example the right number in this one is 5 so u divide 5 by it self and 5 by 45 to get your answer
-3n < 81...divide both sides by -3, change the inequality sign
n > -81/3
n > - 27 <==
** in an inequality, when dividing/multiplying by a negative number, the inequality sign changes
Her claim is reasonable because she can predict how much her skateboard weighs
A^2 - b^2 ...difference of squares
so
9m^4 - 49n^6 = (3n^2)^2 - (7n^3)^2
answer
C. 9m^4 - 49n^6
