H= - 75
A= - 92 (5X + 6)
= - 460X - 522
B = (-6X - 7) (5X + 6 )
= -30X² - 42
C= (-9 X -7)(-10% - 4)
= + 90% X + 28
D= ( -2X -1)(-7X + 3)
= 14X² - 3
--------------------------------
A= - 2n² X(-9)
= 18n²
B= -97 x 6y
= - 592 y
C= - 2t x 5
= - 10t
D= - 7,2 x (-2)
= 14.4
E= 7s - 4s
= 3s
F= 3 x 482 = 1646
H= 7 x 622= 4354
G= 92 x 2 = 184
I= - 6t - 4t = - 10t
------------------------------
A= -662 - 10 = -672
B= - 8X² - 56X
C= 48X -36
D= -60%X + 54X
E= -3(93 +10) = -279 -30 = - 309
F= 9(4X - 10)
= 36X -90
G= (-82-2)100
= (-84)100 = - 8400
H= 9(41-2) = 9(39)= 351
