Это очень просто 3.7 умножить на 3 а потом отнять 4

Answer 3

To find the value of the expression A×3-4 when A is equal to 3 and 7, you simply substitute the values of A into the expression and perform the calculations.

For A = 3: A×3-4 = 3×3-4 = 9-4 = 5

For A = 7: A×3-4 = 7×3-4 = 21-4 = 17

So, the values of the expression A×3-4 are 5 when A = 3, and 17 when A = 7.
