Answer:

Rounded to the nearest hundredths: 11.69.
Step-by-step explanation:
I would use the Pythagorean theorem for this problem.
The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.
Now, just solve using Pythagorean's theorem:

Rounded to the nearest hundredths: 11.69.
I hope this helped you.
Answer:
41.8
Step-by-step explanation:
The rectangles are similar by a factor of 10, so simply divide the measure by 10 to get the length of the smaller one.
Like terms must have the same variables and those variables must have the same powers.
and
are like terms, because they both have
and they both have
.
and
are NOT like terms, because the powers no longer match.
In your example, do you have the same variables and do the variables have the same powers in both expressions?
Answer:
13
