Use FOIL as you described above to multiply the following binomials: (x + 9) (x + 1.

Step-by-step explanation:

FOIL  stands for "First, Outer, Inner, Last"

It is the sum of:

· multiplying the First terms,

· multiplying the Outer terms,

· multiplying the Inner terms, and

· multiplying the Last terms

Example = (a+b)(c+d) = ac + ad + bc + bd

Applying Foil Method we get

(x + 9) (x + 1) =

Now on combining the like terms

(x + 9) (x + 1) =

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
