The fraction he added is 6/30, or 1/5.
I'm not 100% sure about the equation you want me to use but I did the work this way:

5/6+x/30=31/30 (the denominator has to equal 30 because you are adding. You need a common denominator which is why you need to change 5/6. We can label the numerator as a hidden value x)

25/30+x=31/30

You can then work backwards and basically subtract 25 from 31 and get 6; so x=6

The answer is D because in order to find the area of a parallelogram you must multiply the base by the height which is 5 1/4 and 4 1/2.

slava [35]
F ( x ) = - x² + 5 x + 4
between x = 3 and x = 5:
f ( 3 ) = - 3² + 5 · 3 + 4 = - 9 + 15 + 4 = 10
f ( 5 ) = - 5² + 5 · 5 + 4 = - 25 + 25 + 4 = 4
Average rate of change:
( 4 - 10 ) / ( 5 - 3 ) = - 6 : 2 = - 3 feet / sec

Looking for the answer for the second one
FinnZ [79.3K]

Answer:

3 for the left one, and 5 on the right one.

Step-by-step explanation:

The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)

If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.

If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.
