Answer:
24x² -19x-35= 0
24x² -(40-21)x -35= 0
24x²-40x+21x-35=0
8x(3x-5) +7(3x-5)=0
(3x-5) (8x+7)=0
(Ax-5)(2Bx+C) = (3x-5) (8x+7)
Comparing them,
A = 3
B = 4
C= 7
AB-3C = (3×4) - 3(7) = 12-21 = -9
Answer:
Upload the parallelogram or let me know if 5x-5 = 130 degrees and if it is one of the angles of the parallelogram.
Surface area = 2(6*3) + 2(6*2) + 2*(2*3) = 36+24+12 = 72 cm^2
