Anumber has 2 tens and 15 ones. write the number in words

The first thing we must take into account are the following definitions:

tens place: number whose absolute value is greater than zero and which has two digits.

ones place: number whose absolute value is greater than zero and which is located between 0 and tens place.

We then have the following numbers:

2 tens = 2 (10) = 20

15 ones = 15 (1) = 15

Adding both numbers we have:

20 + 15 = 35

Writing the result in the form of a word we have:

35: thirty five

2 tens and 15 ones in words form is:

thirty-five

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
