If 2is the zero of the polynomial f(x)=x^2-8x+k then the value of k is

12

Step-by-step explanation:

zero of the polynomial is 2 ⇒ f(2) = 0

f(2) = 2² - 8 × 2 + k = 0

4 - 16 + k = 0

k = 12

the answer to the expression is 83

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right
