Answer:
Step-by-step explanation:
This is simple: we need to only do 2 steps
1) Convert to feet
2) Get the area
1) Converting to feet is just
(ignore the use of this it's just to show the differnt things to multiply
Now we have a length of 21 and a width of 12 FEET.
2) To solve for the area, we need to multiply both dimensions.

So the answer is 252^2 FEET (DONT FORGET THE UNIT SQUARE FEET)
Hello :
<span>5cosθ = 3cosθ - 1.
</span><span>5cosθ - 3cosθ = 1.
2cos</span>θ =1
cosθ =1/2
all solutions :
cosθ =cos<span>π<span>/3
</span></span>all solutions :
θ =π/3 +2kπ or θ = - π/3 +2kπ ....k in Z
It need to be at least 50 ft long and 50 ft wide.
Step-by-step explanation:
multiply 5x+2y=19 by 3 youll get 15x+6y=57
eliminate y
7x-6y=9
<u>15x+6y=57</u><u> </u> +
22x=66
x=3
substitute x to 5x+2y=19
15+2y=19
2y=4
y=2
