Sometimes stress can be caused by many things. It might even be something that you would have no clue could be causing it. But i suggest telling your parents or someone about it, as posting it on brainly might not be the best idea. Hope you find your answer!

Answer: What you can be experiencing could be known as an overload, you should try to lay back on doing all that work and take a break

Solve 2(x - 1) + 3 = x - 3(x + 1) (make sure to type the number only)

lyudmila [28]

Answer:

x = -1

Step-by-step explanation:

2(x - 1) + 3 = x - 3(x + 1)

Distribute

2x -2+3 = x -3x-3

Combine like terms

2x +1 = -2x-3

Add 2x to each side

2x+1 +2x = -2x-3+2x

4x+1 = -3

Subtract 1 from each side

4x+1-1 = -3-1

4x= -4

Divide by 4

4x/4 = -4/4

x = -1

A solid metal cube of side 1-2 cm has a mass of 15 grams.

sashaice [31]

Answer:

The mass of the second cube is about 1085.07 grams.

Step-by-step explanation:

I assume '1-2 cm' means 1.2cm here. Correct me if I am wrong and I'll edit my answer.

First, find the density of this cube:

$d=\frac{m}{v}$

where d is density, m is mass, and v is volume.

We have one of those, but we also need volume. The volume of a cube is just:

$v=a^3$

where a is the length of a side.

$\rightarrow v=1.2^3\\\rightarrow v=1.728$

The volume of this cube is 1.728cm³. Now, you can find the density;

$\rightarrow d=\frac{15}{1.728}\\\rightarrow d\approx8.6806$

The density of this material is about 8.68 grams per cubic centimeter.

Finally, you can use that density to find the mass of the other cube. Fin the volume of the second cube:

$\rightarrow v=5^3\\\rightarrow v=125$

The volume is 125cm³. Given the density and the volume, you can calculate the mass:

$\rightarrow d=\frac{m}{v}\\\rightarrow 8.6806=\frac{m}{125}\\\rightarrow 8.6806\times125=m\\\rightarrow m=1085.0694$

The mass of the second cube is about 1085.07 grams.
