Question

(3x+20) 4x (10x-16)​

Answer 1

Step-by-step explanation:

$(3x + 20)4x(10x - 16) \\ = (3x + 20)(5x - 8)8x \\ = 15 {x}^{2} + 100x - 24x - 160 \\ = 15 {x}^{2} + 76x - 160$

I am assuming that all the polynomials are in multiplication..

Answer 2

Step-by-step explanation:

=(3+20)4×(10 -16)

=32 + 4× 6

=32+32

=64
