Answer:
30 minutes
Step-by-step explanation:
First you can break down the percent and the time into a fraction
You can divide it by 2
so 2%/1 (2% in 1 minute)
Then you find the amount of time it would take to paint the whole bookcase
2 * 100 = 50
So time to paint the whole bookcase would be 50
50 - 20 = 30

Answer:
A
Step-by-step explanation:

notice where how many "yes" sign change happen in the positive "x"
and the on the negative "-x"
for the P(x) is 3 changes, thus
so is either 3 real positive ones, or 3-2 = 1 real positive one
P(-x) gives no sign changes, so there are 0 negative ones
the polynomial has a degree of 5, thus 5 roots
if it has 3 real positive ones, then it has 2 complex ones
the complex ones pick up the slack per se
if it has 1 real positive one, then it has 4 complex ones
bear in mind complex ones always come in pairs
