Answer:

(f+g)(x) = -4^x + 5x - 2

Step-by-step explanation:

if f(x) = -4^x - 8 and g(x) = 5x + 6,

(f+g)(x) = f(x) + g(x)

= -4^x - 8 + 5x + 6

= -4^x + 5x - 2

Answer:

-4^x + 5x - 2

Step-by-step explanation:

By the additive property of function, (f+g)(x) = f(x) + g(x)

Given f(x) = -4^x - 8 and g(x) = 5x + 6

(f+g)(x) = f(x) + g(x)

= -4^x - 8 + 5x + 6

= -4^x + 5x - 2

the volume of cube A is 216 cubic inches. the length of each edge in cube B is 2 inches longer than the length of each edge in c

Aleonysh [2.5K]

If the side lengths of B are 2x as long as the side lengths of A then the volume of B should be the volume of A^2
216^2=46,656
46,656-216=46,440

This can be more easily displayed with smaller numbers

If cube X were 2*2*2 then the volume would be 8
If cube Y were 4*4*4 then the volume would be 64
8(volume of cube X)^2=64(volume of cube Y)

A cube has edges that are 3 inches in length. How many of these cubes will it take to completely fill a larger cube that has an

lorasvet [3.4K]

Step-by-step explanation:

We will divide the volume of the larger cube with that if the smaller cube. However, we’ll first have to convert them to the same SI units;

12 inches = 1 foot

Therefore the volume of the larger cube;

12 * 12 * 12 = 1728 inches cubed

The volume of the smaller cube;

3 * 3 * 3 = 27 inches cubed

Divide the two;

1728/27

= 64
