Question

Створіть вираз: а) 13х+2х; б) 15к+24к_9к; в) 72р-8р-р.

Answer 1

a) 13х + 2х

To simplify the expression 13х + 2х, we can combine the like terms, which means adding or subtracting the coefficients of the same variable. In this case, both terms have the variable 'х', so we can add the coefficients 13 and 2.

Adding 13 and 2 gives us 15. Therefore, the simplified expression is:

15х

б) 15к + 24к - 9к

To simplify the expression 15к + 24к - 9к, we can combine the like terms. All three terms have the variable 'к', so we can add or subtract their coefficients.

Adding 15, 24, and -9 gives us 30. Therefore, the simplified expression is:

30к

в) 72р - 8р - р

To simplify the expression 72р - 8р - р, we can again combine the like terms. All three terms have the variable 'р', so we can add or subtract their coefficients.

Adding 72, -8, and -1 gives us 63. Therefore, the simplified expression is:

63р
