Answer:

a) \:  \: 6x - 8

b) \:    \: - 18 {x}^{2}  + 15

c) \:  \:  {x}^{4}  + 2  {x}^{3}  + 7 {x}^{2}

Step-by-step explanation:

a) \:  \: 2(3x−4) \\ 2(3x)+2(−4) \\ 6x+2(−4) \\ 6x−8

b) \:  \: −3(6 {x}^{2} −5) \\ −3(6 {x}^{2} )−3( - 5) \\  - 18 {x}^{2}  - 3( - 5) \\  - 18 {x}^{2}  + 15

c) \:  \:  {x}^{2} ( {x}^{2}   + 2x + 7) \\  {x}^{2}   {x}^{2}  +  {x}^{2} (2x) +  {x}^{2}  \times 7 \\  {x}^{4}  + 2 {x}^{2} x + 7 \times  {x}^{2}  \\  {x}^{4}  + 2  {x}^{3}  + 7 {x}^{2}

Step-by-step explanation:

To predict: the probability of the coin landing heads up
