Answer: 289 is a semi-prime number that is created by doing 17 times 17. 17 is a prime number though. hope this helps.
Step-by-step explanation:
289
17 17
the equation 2x-4-1+x would be the answer
Because 2x+x = 3x and -4-1 = 5, the result would be 3x-5
Answer:
1) Change the length of side AB to 2 feet
Step-by-step explanation:
Given that both structures are similar, it follows that the ratio of their corresponding lengths are equal.
To find out what should be the correct length of AB that she should change to, set up the proportion showing the ratio of 2 corresponding lengths of both structures. Thus:

We will assume AB is unknown.
PR = 7.5 ft
AC = 2.5 ft
PQ = 6 ft
Plug in the values into the equation

Cross multiply


Divide both sides by 7.5

The architect should change the length of AB to 2 ft
Lol I don't know how to make a table on this site, but I will try!

health: __7__⊥__14___⊥__21__⊥__28_
fire: 12 ║ 24 ║ 36 ║

There are not any common factors between 7 and 12 until they are multiplied
The health inspector and the fire inspector will visit on the same day in 84 days
Hope I helped! Comment if you have a question about my answer! :)
The answer would be A 360
