Assume that the expression 4x5 in the question is 4x5.4x5 = 3 : x5 = 3/4 : x = 5√(3/4) : then 2k.5√(3/4) + 10 = 2 : 2k.5√(3/4) = 2 - 10 = -8 :k = -4 ÷ 5√(3/4) = -4 ÷ 0.9441 = -4.2369 (4dp)
9x + 5 = 5x + 179x + 5 - 5x = 179x - 5x = 4x5-4x=1717-5=1212 divided by 4 = 3x=3
4+5-4x5 First you do 4x5=20 Then 4+5=9 So you have 9-20=-11 Your answer is -11
having the property that one term operating on a second is equal to the second operating on the first, as an example: 4x5=5x4 or 5x4=4x5 RATE MY ANSWER THE BESTEST OF ALL!!!!
