1) which statement is true about this argument?
premises: if a polygon has six sides, then it is a hexagon. polygon abcdef has six sides.
conclusion: polygon abcdef is a hexagon.
a) the argument is not valid because the conclusion does not follow from the premises.
b) the argument is valid by the law of detachment.
c) the argument is valid by the law of syllogism.
d) the argument is not valid because the premises are not true.

their is no graph showing

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

ome people is not even worth it to even try it in the air.
