19 has 2 factors (1,19)
21 has 4 factors (1,3,7,21)
23 has 2 factors (1,23)
25 has 3 factors (1,5,25)
you need the nearest number 25 that has 5 factors or more :28(1,2,4,7,14,28)

Answer:

The possible number is 28.

Step-by-step explanation:

Since,

Factors of 19 = 1, 19,

Factors of 21 = 1, 3, 7, 21,

Factors of 23 = 1, 23,

Factors of 25 = 1, 5, 25

Now, numbers greater than 25 are,

26, 27, 28, 29, ......

Factors of 26 = 1, 2, 13, 26,

Factors of 27 = 1, 3, 9, 27,

Factors of 28 = 1, 2, 4, 7, 14, 28

Hence, a number greater than 25 that has more factors than the number 19, 21, 23 and 25 would be 28.

Can someone and give me the right answer

kolezko [41]

The 1st option is your answer,

because to solve c, the -11 and 11 = 0, so your left with adding 23 and 11, then you divide -4 on both sides to get the variable (x) by itself

And for f, you only need to divide -4 on both sides to get x by itself.
