For what value of p,-4 is a zero of the polynomial x square-2x-(2p+3)

We have that
x²-2x-(2p+3)

if -4 is a zero of the polynomial
so
for x=-4
x²-2x-(2p+3)=0> (-4)²-2*(-4)-(2p+3)=0> 16+8-2p-3=0
21-2p=0
2p=21
p=21/2> p=10.5

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
