Step 2...first error...when distributing through the parenthesis, u multiply, not add.
4(2x - 4) = 8 + 2x + 8 =
8x - 16 = 16 + 2x <== correction
(3a^4 * b^-2) * (2a^7 * b^-1)
= 6*a^(4+7)*b^(-2-1)
= 6*a^11*b^-3
Put the first number on top then start adding 6+0, 8+1, 0+4, 1+1, 0+0 and the answer is 69420
3. C
4. 2
5. C
hope this helps:)
$40=T >?=m
T= $40,$80,$120,etc.
m=1,2,3,etc
