The answer is wrong because it's meant to be ....

3x x 2 =15 so do the reverse !
15/3 = 5/2 = 2.5
Double check by putting it in the formulae

3(2.5) x 2 = 15

PLEASE HELP:<br> Solve for x.<br><br> 3(x-1) - 4x greater than or equal to -3

shutvik [7]

Our inequality is 3(x-1) - 4x ≥-3. We can solve this like we solve for x in a regular equation. If I multiply 3(x-1), our new inequality is 3x -3 - 4x ≥ -3. If we add 3 to both sides and subtract 4x from 3x we have -x ≥ 0. But we want the value of x to be positive, not negative. So we multiply both sides by -1 and change the sign from greater than to less than. We get x<span> ≤ </span>0.

Step-by-step explanation: The sides lengths are 25 cm and 17 cm. And to get parameter you have to add all the sides. So, it would be 25 + 25 + 17 + 17.
