Answer
A. $6x^{2}+23x+20$
Work Step by Step
We are given the expression $(2x+5)(3x+4)$. We can find the product of this expression using the FOIL method.
First terms: $2x\times 3x=6x^{2}$
Outer terms: $2x\times4=8x$
Inner terms: $5\times 3x=15x$
Last terms: $5\times4=20$
Adding together: $6x^{2}+8x+15x+20=6x^{2}+8x+15x+20=6x^{2}+23x+20$
