This is important question
Michael is putting a frame around a rectangular photograph. The photograph is 10 inches long and 8 inches wide. The frame has a uniform width of x.

What is the entire length of the frame? (__+__x)

What is the entire width of the frame? (__+__x)

Then give the area of the entire framed picture from the problem above in standard form.

(__x^2+__x+__)in^2

Aking and his army will attempt to capture a fortress. the left and right flanks break off from the main group to attack the west and east guard towers. suppose the left flank has a 60% chance of success and the right flank has a 75% chance of success, independently of one another. if both flanks capture their respective targets, then the king has a 98% chance of successfully taking the fort. if, however, only the left flank captures its tower, the king has an 80% chance of success; if only the right flank succeeds, the king has a 50% chance. if both flanks fail, then the king's chance of capturing the fort drops to 20%. it turns out the king captures the fort. what is the probability that one, and only one, flank was successful (either the left, or the right, but not both)? (round your answer to 3 decimal places)
