1 answer:

4 0

Given:
square based pyramid = 3.5 cm base
side length = 7 cm

Base Area = (3.5cm)² = 12.25cm²

Surface Area = Base Area + 2sl = 12.25cm² + (2 * 3.5cm* 7cm)
S.A = 12.25 cm² + 49 cm²
<span>S.A = 61.25 cm² </span>

Let f(x)=2x^2+x-3 and g(x)=x-1 perform the indicated operation, then find the domain. f/g(x)

Ray Of Light [21]

F(x) = 2x² + x - 3
g(x) = x - 1
(f - g)(x) = (2x² + x - 3) - (x - 1)
(f - g)(x) = 2x² + (x - x) + (-3 + 1)
(f - g)(x) = 2x² - 2
