10 -> f

Step-by-step explanation:

1) (3+7x)(6+2x)

    = 18+6x+42x+14x²

    =14x²+48x+18

2) (2u³-5u²-7u)(3u³+4u²)

     =6u⁶+8u⁵-15u⁵-20u⁴-21u⁴-28u³

     =6u⁶-7u⁵-41u⁴-28u³

3) (x+3)(2x²+10x+1)

       =2x³+10x²+x+6x²+30x+3

       =2x³+16x²+31x+3

4) (-6y²-6y)(-7y²-7y)

        =42y⁴+42y³+42y³+42y²

        =42y⁴+84y³+42y²

5) (5+x)(2x-10)

        =10x-50+2x²-10x

        =2x²-50

6) (2k³-4k²-4k)(7k²+2k)

        =14k⁵+4k⁴-28k⁴-8k³-28k³-8k²

        =14k⁵-24k⁴-36k³-8k²

7) (x-x²)(x²-x)

        =x³-x²-x⁴+x³

        =-x⁴+2x³-x²

8) (2u³-5u²-7u)(3u³+4u²)

        =6u⁶+8u⁵-20u⁴-21u⁴-28u³-21u⁴

        =6u⁶+8u⁵-41u⁴-28u³

9) (jk+xy)(7jk+9xy)

        =7j²k²+9xyjk+7jkxy+9x²y²

        =7j²k²+16xyjk+9x²y²

10) (-2y)(7y³-4y²)

        =-14y⁴+8y³
