Answer:

Natural numbers between 75^{2} and 76^{2} is

(76 * 76) - (75 * 75)

=> 5776 - 5625

=> 151

Therefore, there are 151 natural numbers between 75^{2} and 76^{2}

Solve the systems by the addition method 2x + y = - 1x - 2y = - 4
inna [77]

Answer:

x = -6/5

y =7/5

Step-by-step explanation:

2x + y = - 1

x - 2y = - 4

Multiply the first equation by 2 so we can eliminate y

2(2x + y = - 1)

4x + 2y = -2

Add this to the second equation

4x + 2y = -2

x - 2y = - 4

---------------------

5x + 0y = -6

Divide by 5

5x/5 = -6/5

x = -6/5

Multiply the second equation by -2 so we can eliminate x

-2(x - 2y = - 4)

-2x+4y = 8

Add this to the first equation

2x + y = - 1

-2x+4y = 8

---------------------

0x + 5y = 7

Divide by 5

5y/5 = 7/5

y =7/5

5. Find the lateral surface area of the net of<br> the cube.<br> 1.8 cm
igor_vitrenko [27]

<u>Given</u>:

Given that the side length of the cube is 1.8 cm

We need to determine the lateral surface area of the cube.

<u>Lateral surface area of the cube:</u>

The lateral surface area of the cube can be determined using the formula,

LSA=4a^2

where a is the side length.

Substituting a = 1.8 in the above formula, we get;

LSA=4(1.8)^2

Squaring the term, we get;

LSA=4(3.24)

Multiplying, we get;

LSA=12.96

Thus, the lateral surface area of the cube is 12.96 cm²
