Question

Запишите и упростите: А)Сумму выражений -19+р и -16-р Б)Разность выражений -а+б и -а-б

Answer 1

А) (-19 + р) + (-16 - р) = -19 + р -16 - р = -35
б) (-a + b) - (-a - b) = - a + b +a + b =2b

Answer 2

Calculations:

A) Sum of the expressions -19r and -16r: The sum of the expressions -19r and -16r can be calculated by adding the coefficients of r. The sum is: -19r + (-16r) = -19r - 16r = -35r.

B) Difference of the expressions -a-b and -a-b: The difference of the expressions -a-b and -a-b can be calculated by subtracting the second expression from the first. The difference is: (-a-b) - (-a-b) = -a - b + a + b = 0.
