Пошаговое объяснение:

(25а-32b)•5 при а=40 b=5

(25а-32b)•5= 125а-160b=125*40-160*5=5000-800=4200


aldiyarkairulla: Не правильно
aldiyarkairulla: 5040
Sofiiren: по условию, которое написал автор все правильно ответ 4200
Sofiiren: не надо писать какой ответ правильный, подставили в данное условие значения а и b и решили. А если изначально условие записано не верно , то это вопрос к автору .
Sofiiren: Если бы условие было (25a-32b)•6 при а=40 b=5 тогда ответ 5040, но смотрите условие разность умножается на 5 , а ни на 6. Так , что прежде чем написать, что ответ не правильный смотрите условие.
