Question

6A+6B-2^3 при A+B=225

Answer 1

6*(А+В)-8=6*225-8=1350-8=1342

Answer 2

6А+6В-2^3=6*(А+В)-2^3=6*225-8=1350-8=1342

Answer 3

To evaluate the expression 6A + 6B - 2^3 given that A + B = 225, you need to substitute the value of A + B into the expression and then perform the calculations. Let's do that step by step:

Step 1: Replace A + B with 225 in the expression. 6A + 6B - 2^3 = 6(225) + 6(225) - 2^3

Step 2: Perform the operations inside parentheses and exponentiation. 6(225) = 1350 2^3 = 2 * 2 * 2 = 8

Step 3: Substitute the calculated values back into the expression. 6A + 6B - 2^3 = 1350 + 1350 - 8

Step 4: Perform the final calculations. 6A + 6B - 2^3 = 2692

So, when A + B = 225, the value of the expression 6A + 6B - 2^3 is 2692.
