Multiply (3x-+4) and use distributive property and simply

-3x² +17x -20

Step-by-step explanation:

Hi, to solve this we have to apply distributive property.

To do this, we have to multiply each addend separately and then add the products.

(3x-5)(-x+4)  

(3x.-x) (3x.4) (-5.-x) (-5.4)

-3x² +12 x+5x-20

Adding alike terms to simplify (in this case 12x + 5x)

-3x² +17x -20

Feel free to ask for more if needed or if you did not understand something.

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
