Nimfa-mama [501]

Answer:

20 cm

Step-by-step explanation:

A cube has 6 faces. Two of the faces are bases. The other four faces are lateral faces.

Let the area of 1 face = x

4x = 1600 cm^2

x = 400 cm^2

Since the area of 1 face is 400 cm^2, then the side length is sqrt(400 cm^2) = 20 cm

Answer: 20 cm

F(x) =2x+1 and g(x) =x^2-7 find (f+g)(x)

GaryK [48]

$f(x) = 2x + 1 \ \ and \ \ g(x) = {x}^{2} - 7$

$(f \ \ + \ \ g)(x) = f(x) + g(x)$

$(f \ \ + \ \ g)(x) = 2x + 1 + {x}^{2} - 7$

$\boxed{(f \ \ + \ \ g)(x) = {x}^{2} + 2x - 6}$
