4x(x + 5) -3(x + 5)

Factor out the common term x + 5

Answer:

Mochi

Step-by-step explanation:

Mochi

Each week theres a increase of 4 in Mochi's weight. So you will add 4 twice to get to the 5th week.

4th week : 17

5th week : 21

Kappa

In 4 weeks Kappa weighed 14, which is less that Mochi at the pace Kappa is going at.

on the 3rd week Kappa weighed 11

and 2nd week Kappa weighed 5

and 1st week Kappa weighed 3

Looking at the graph, we can give a rough estimate on the 5th week it's going to be 16 or 17 either way making Mochi heavier.

URGENT HELP PLS PLS PLS
Gennadij [26K]

Answer:

15 kg

Step-by-step explanation:

Radius of a solid sphere : mass of a solid sphere

3 cm : 9 kg

Find the mass of a sphere of the same material of radius 5 cm

Radius of a solid sphere : mass of a solid sphere

5 cm : x kg

Equate both ratios to find x

3 cm : 9 kg = 5 cm : x kg

3/9 = 5/x

3 * x = 9 * 5

3x = 45

x = 45/3

x = 15 kg

The mass of a sphere of the same material of radius 5 cm is 15 kg
