$x = 50 \% \text { of } 20$

$x = \frac{50}{100} \times 20$

$x = 10$

Hence, the total number of classmates who liked to make Jewellery = 10

F(x)=2x^2+3 & g(x)=x^2-7 find (f-g)(x)

kicyunya [14]

Answer:

$\boxed{\sf (f - g)(x) = x^2 + 10}$

Given:

f(x) = 2x² + 3

g(x) = x² - 7

To Find:

(f - g)(x)

Step-by-step explanation:

(f -g)(x) = f(x) - g(x)

= (2x² + 3) - (x² - 7)

= 2x² + 3 - x² + 7

= 2x² - x² + 3 + 7

= x² + 3 + 7

= x² + 10
