Which is true about the degree of the sum and difference of the polynomials 3x©y - 2xy - 7xy and 8x®y + 2xy + xy2
Both the sum and difference have a degree of 6.
Both the sum and difference have a degree of 7.
The sum has a degree of 6, but the difference has a degree
The sum has a degree of 7, but the difference has a degree of 6.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

$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
