Answer:
50
Step-by-step explanation:
The discount is $.40 (1.20 - 0.80)
To find the discount you take (0.40/1.20) * 100
=.33 * 100
The discount is 33%
445 i think … i did 49 x 5 = 245 and then 40 x 5 = 200 and added 200+245 = 445
Hello from MrBillDoesMath!
Answer:
-5, 0 (multiplicity 2), +4
Discussion:
Let f(x) = x^4 + x ^3 - 20 x^2
Factor x^2 from each term:
f(x) = x^2 ( x^2 + x - 20) = x^2 ( x +5) (x-4)
f = 0 when x = 0 (multiplicity 2) and x = -5 or x = 4
