Question

A+1-4a = ?1. a= -22. a= -1 3. a= 04. a=15. a=2​

Answer 1

Ответ:

1. -2+1-4×(-2)= -1+8=9

2.-1+1-4×(-1)=0+4=5

3.0+1-4×0=1

4.1+1-4×1=2-4= -2

5.2+1-4×2=3-8= -5

Answer 2

It seems like you have provided a mathematical expression involving the variable "a" and some values for "a". Let's substitute these values into the expression and calculate the results:

Given expression: A + 1 - 4a

1. For a = -22: Result: A + 1 - 4(-22) = A + 1 + 88 = A + 89

2. For a = -1: Result: A + 1 - 4(-1) = A + 1 + 4 = A + 5

3. For a = 0: Result: A + 1 - 4(0) = A + 1

4. For a = 1: Result: A + 1 - 4(1) = A + 1 - 4 = A - 3

5. For a = 5: Result: A + 1 - 4(5) = A + 1 - 20 = A - 19

6. For a = 2: Result: A + 1 - 4(2) = A + 1 - 8 = A - 7

Please note that the result of the expression depends on the value of "A" as well. If you have a specific value for "A," you can substitute it in the results above to get the final numerical values.
