Answer:

The value of k is 14.

Step-by-step explanation:

(x - 2) is a factor of the polynomial

$x - 2 = 0 \rightarrow x = 2$

This means that $p(2) = 0$

p(x) = 2x² + 3x - k

$p(2) = 2(2)^2 + 3(2) - k$

$0 = 8 + 6 - k$

$14 - k = 0$

$k = 14$

The value of k is 14.

Answer:

The cost of 6 cans of soup = $7.8

Step-by-step explanation:

The cost of 10 cans of soup = $13

The number of cans needed for the soup = 6

Now, Cost of 1 can of soup = $\frac{\textrm{Total cost of 10 cans of soup}}{\textrm{10}}$

= $13 / 10 =$1.3

⇒The cost of 1 can of soup is $1.3

Now, The cost of 6 cans of soup = 6 x Cost of 1 can

⇒ 6 x $1.3 = $7.8

Hence, the cost of 6 cans of soup = $7.8
