Question

A := -3 b:= (a+7) - a b := b - a c := (-b*a) - (a*a)

Answer 1

Ответ:

Объяснение:

a:= -3

b:=(а+7) - а

b:= b - a

c:= (-b*a)-(a*a)

b:= (-3+7) - (-3) = 4 + 3 = 7

b:= 7 - (-3) = 7 + 3 = 10

c:= (-10*(-3)) - (-3*(-3)) = 30 - 9 = 21

Answer 2

It seems like you've provided a sequence of arithmetic operations involving variables A, a, b, and c. Let's break down each step:

1. A := -3 Here, you're assigning the value -3 to the variable A.

2. b := (a+7) - a In this step, you're assigning a value to the variable b. The value is calculated by adding 7 to the value of variable a and then subtracting the value of variable a itself. This simplifies to just 7.

3. b := b - a You're updating the value of variable b by subtracting the value of variable a. If we substitute the previously calculated value of b (which is 7), this operation becomes: b = 7 - a.

4. c := (-ba) - (aa) Here, you're assigning a value to the variable c. The value is calculated by multiplying the negative value of b with the value of variable a and then subtracting the square of the value of variable a. This can be simplified as: c = -7a - a^2.

So, in summary:

• A = -3
• b = 7 - a
• c = -7a - a^2
