Question

please answer this ​

Answer 1

Step-by-step explanation:

1. 2b(4x+5b)

= 8bx+ 10b²(Answer)

2. -3c(4x-5y)

= -12xc+15cy(Answer)

3. 2x(3x-y)+3y(3x-y)

= 6x²-2xy+9xy-3y²

= 6x²+7xy-3y²(Answer)

4. 4x-5-3x²+7x-8

= 4x+7x-5-8-3x²

= 11x-13-3x²(Answer)

Thank you

Answer 2

1. 2b( 4x+5b)= 8xb+ 10b²

2. -3c(4x-5y)= -12xc+15cy

3. (2x+3y)(3x-y)= 6x²+7xy-3y²

4. (4x-5)-(3x²-7x+8)= 3x²+11x–13
