Answer 1

Answer:

$=7x^2+8x-2$

Step-by-step explanation:

So, on Monday, Tuesday, and Wednesday, he mowed:

$(4x^2+3x-4),(5x-8),(3x^2+10)$

yards, respectively.

To determine how many yards he mowed in the three days, simply add the three expressions. Thus:

$(4x^2+3x-4)+(5x-8)+(3x^2+10)$

Combine like terms:

$=(4x^2+3x^2)+(3x+5x)+(-4-8+10)$

Add or subtract:

$=7x^2+8x-2$

And it cannot be simplified further :)
