Объяснение:

В общем реши на калькуляторе:8×2,5+12×2,5×(-3)+6×2,5×(-3)+(-3) и всё, осталось только забить

Answer 2

To evaluate the expression 8a + 12ab + 6ab + b with the given values a = 2.5 and b = -3, we substitute these values into the expression and perform the calculations:

8a + 12ab + 6ab + b = 8(2.5) + 12(2.5)(-3) + 6(2.5)(-3) + (-3) = 20 + 12(2.5)(-3) + 6(2.5)(-3) - 3 = 20 + 12(-7.5) + 6(-7.5) - 3 = 20 - 90 + (-45) - 3 = -53

Therefore, when a = 2.5 and b = -3, the expression 8a + 12ab + 6ab + b evaluates to -53.
