ok when you first loaded the x y z fraction question on another page you asked for help where two people had answered saying it was 3 they were wrong the answer is 6 as 18/3 = 6 the answers below are for this question above hope this helps you also
Step-by-step explanation: QU 1 = 50 + QU 2 = 1
Qu 1) -5 a + 2b - 6c = rewrite out empty brackets for a and b and c Then step 2 is to input number's in brackets as a = -6 b = 4 and c = -2 we substitute so write out first (-5 ( )) + 2( ) - (6( )) if all polynomials are + - we show so like in bold then its easier to determine what to fill in to substitute (-5 (-6)) + 2(4) - (6(-2)) = 30 + 8 + 12 = 50 if we rewrote like this instead (-5 (-6)) + 2(4) -6(-2)) it would also be right so the answer is 50 Qu 2) sq rt 5x +2 y = (when x = 5 and y = -2) sq rt 5(5) and + 2(-2) = sq rt 25 -4 = 5 -4 = 1 Hope this helps also free worksheet info for graphs to explain things math.utah.edu/~wortman/1050-text-calp.pdf just type www in front helps all students that are struggling with graphs
