1. solve each equation, system of equations, or inequality.
a) x4 +4x3 -10x2 -28x-15=0 given (x – 3) and (x + 1) are factors to the polynomial f(x)=x4 +4x3 -10x2 -28x-15
b) x3 -8x-7=0 given (x + 1) is a factor for the polynomial h(x)=x3 -8x-7

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

won't that be plagrisim thought?
