Question

Simplify 2x 2 - y for x = 3 and y = -2. A:10 B:16 C:20 D:14

Answer 1

Answer:

20

Step-by-step explanation:

Given,

X = 3

y = -2

Now,

$2 {x}^{2} - y$

Plugging the value of X and y

$2 \times {(3)}^{2} - ( - 2)$

Calculate the product

$= 2 \times 9 - ( - 2)$

$= 18 - ( - 2)$

$= 18 + 2$

$= 20$

Hope this helps...
