Explain why solving the equation - 3n - 4 = 2 is different from solving the

Klio2033 [76]3 years ago

Answer:

Step-by-step explanation:

First get the answer to -3n - 4 = 2

-3n - 4 + 4 = 2 + 4

-3n = 6

n = 6/-3

n = -2

That answer is the only one that is permitted. It is the only one that completely satisfies the equation.

Now when you do the inequality, look what happens.

-3n - 4 < 2              Add 4 to both sides.

-3n-4+ 4 < 2+4

-3n < 6                  Now there are a bunch of ways (2) to solve this.  

                            No matter which way you do it, the arrow will change.

-3n/-3 > 6/-3

n > - 2

That means that any number that is greater than - 2 will satisfy the inequality.

So n = 0 will work. Even n = - 1 will work. Anything bigger than -2 will work. The equation does not provide that kind of latitude.

isaacs new panoramic television is 40 inches and 9 inches high. what is the diagonal size of Isaac’s television?
jekas [21]

Answer:

41 inches

Step-by-step explanation:

To solve for the diagonal length of his television, we can use the formula:

a² + b² = c²

Square the length and width of the TV then add them together. Then find the square root of the sum.

40² = 1600

9² = 81

1600 + 81 = 1681

√1681 = 41

The length of the small leg of a 30 -60 -90 degree triangle is 5. What is the perimeter of the triangle?
vivado [14]

Answer:

option (B)

15 + 5√3

Step-by-step explanation:

In a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.

Given in the question,

length of small leg = 5

As we know that

The hypotenuse is equal to twice the length of the shorter leg

<h3>hypotenuse = 2(5) =10</h3>

The longer leg is equal to multiplying the shorter leg by the square root of 3

<h3>other leg = 5√3</h3>

Perimeter of a triangle = sum of the length of three sides

                                     =  5√3 + 10 + 5

                                     = 15 + 5√3
