6 0

Step-by-step explanation:

x³ - 4x = 0

x (x² - 4) = 0

x (x + 2) (x - 2) = 0

Thus the answer is (b) (-2 , 0) , (0 , 0) , (2 , 0)

If a fair six-sided die is rolled three times, what is the chance of getting at least one ace ? note: an ace is the number 1.
qwelly [4]
Recall that the probability of multiple events occurring is equal to their individual probabilities. The chance of rolling a one is 1/6, so the chance of that occurring three times is (1/6)^3, which is equal to 1/216.

What is the value of x
Gemiola [76]
For this case, we observe that the triangles are similar.
 We observe that the triagnules have three equal angles.
 Therefore, to find the value of x we can use the following relationship:
 x / 15 = 5/12

 Clearing x we have:
 x = (5/12) * (15)

x = 6.25
 Answer:
 
The value of x is given by:
 
x = 6.25

In a school of 685 students, there are 385 students involved in sports teams, and there are 450
Cerrena [4.2K]

Answer:  a) see image (below)

                b) S ∩ M = 237

                c) S U M = 598

<u>Step-by-step explanation:</u>

b) Total students = 685

   Not sports or music = 87

   Sports Total = 385

   Music Total = 450

Both Sports and Music is their intersection:

S ∩ M = S + M + N -  T

          = 385 + 450 + 87 - 685

          = 237

c) Sports only = S - (S ∩ M)

                       = 385 - 237

                       = 148

Music only = M - (S ∩ M)

                  = 450 - 237

                  = 213

Sports OR Music is their union:

S U M = S + M - (S ∩ M)

          = 385 + 450 - 237

          = 598

Question no 7 please solve answer for brain liest
rewona [7]

Answer: 76 rows.

Step-by-step explanation:

The gardener has 5770 plants.

Now, suppose that he plants M rows of plants, such that each row has N plants on them

Then the total number of plants is M*N

And he wants to have the same number of rows that plants in each row, then:

M = N

Then the total number of plants is M*M = M^2

Now we know that he falls short by 6 plants, then we have the equation:

M^2 = his total number of plants + 6 plants

M^2 = 5770 + 6 = 5776

We can solve this for M, as:

M = √(5776) = 76

This means that the gardener wants to make 76 rows.
