A rectangular photograph is surrounded by a border that is 1 inch wide on each side. The total area of the photograph and the bo

rder is M square inches. If the border had been 2 inches wide on each side, the total area would have been (M + 52) square inches. What is the perimeter of the photograph, in inches?

if 1 inch is added, you would add 2 inches to to each side of rectangle.  

You would have: W+2, and, L+2,  

Now let W+2 = x and, L+2 = y  

Total area =  x*y=M  

If 1 inch is added again, like above you add 2 inches to both sides, you would then have:

(x+2)(y+2)=M+52;  

xy+2x+2y+4=M+52;  

xy=M

2x+2y=48  

x+y=48/2=24  

Now solve :

W+2+ L+2=24  

W+L=20  

The perimeter is 2(W+L)=20*2 = 40 inches.

Which of the following inequalities is graphed on the coordinate plane
azamat

Answer:

The answer is D.

Step-by-step explanation:

Well, all the equations are the same except for the symbol so you don't need to figure out the equation of the line.

Anyways, note that the line is dotted, which means it cannot be A nor B since they have an "equal to."

Also, note that the shaded region is above the graph. Since it is above, it means that y is greater than whatever x is.

Thus, the answer is D.

Find the volume V of the cone. Round your answer to the nearest tenth.
uranmaximum [27]
The volume of cone formula is 1/3 times pi times radius^2 times height. So in this case the formula which numbers substituted in would be 1/3 times pi times 8^2 times 12. The final answer would be 804.2477 and if rounded it would be 804.2 m^2
