А. х²-4=0; х²=4; х=±2, true.
B. x²=-4; there is no solution.
C. 3x²+12=0; 3x²=-12; x²=-4; there is no solution.
D. 4x²=16; x²=4; x=±2, true.
E. 2(x-2)²=0; 2(x²-4x+4)=0; 2x²-8x+8=0; x²-4x+4=0; x1=2; x2=2. False. The answer: A, D.
Heyo, I believe the answer is 44 since we're talking about inscribed angles which is 1/2 of the arc length so 88/22=44
-3/4, -7/10, 3/4, 8/10 is least to greatest
$57.50÷10=5.75 so that means for every 1 hour you get payed 5.75
LCM the last common multiple. the greatest common factor is the biggest number that will go into the 2 numbers so it can be no bigger than the 2 numbers. the LCM is larger than at least one of them
