In a collection of 50 cards, Sal has some valuable and some regular cards. He has 16 more valuable cards than regular cards. How many of each kind of card does Sal have? Explain the situation using an equation and solve.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

$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

i agree because i see the other persons thinking is clear

it has to have an angle of 90 degrees
