t = 
multiply both sides by 6rt
6crt = 1 ( divide both sides by 6ct to obtain r )
t = 
Answer:
16 x units
Step-by-step explanation:
Perimeter of a original square= 8 x units
Perimeter of a square= 4× side
Side of a square = 
Side of a square = 
Side of a square= 2 x units
since four square are joined together to form a single square
So each side of a bigger square= 4 x units
Perimeter of a new bigger square= 4 × 4 x units
Perimeter of a new bigger square= 16 x units
Hence, the correct answer is 16 x units
Answer:
12(5x-y)
Step-by-step explanation:hope this help
we know that
if two lines are parallel
then
their slopes are equal
Step 1
Find the slope of the line 2x + 5y = 4
2x + 5y = 4------> 5y=4-2x-----> y=(4/5)-(2/5)x------> slope m=(-2/5)
step 2
with m=-2/5 and the point (5, –4) find the equation of the line
y-y1=m*(x-x1)------> y+4=(-2/5)*(x-5)----> y=(-2/5)x+2-4
y=(-2/5)x-2
therefore
the answer is the option D
Answer:
12π
Step-by-step explanation:
Volume of the cone is πr^2 * h / 3
r = 3
h = 4
9π * 4 / 3 = 12π
