Answer:
The answer could be either 10 or -7
Step-by-step explanation:
(w-3)(w)=70
w^2 -3w=70
w^2 -3w-70=0
(w-10)(w+7)=0
w=10 or -7
54 divided into 9 tenths. When dividing by decimals, the number becomes greater, because the decimal is less than 1 whole unit. The answer is 60.
3w(w) = 48
3w^2 = 48
w^2 = 48/3
w^2 = 16
w = sqrt 16
w = 4
