Answer should be b, not 100% sure
You can do this by replacing x = -2y + 10 in second equation and solving for y then plug this value of y in first equation to find x then use these values of x and y in last equation to find zSHOW FULL ANSWER

Answer: 2</h3>
========================================================
Explanation:
If a number only has one factor pair, then that number must be prime. This is because prime numbers only have factors of 1 and the number itself.
For instance, the value 7 is prime because the only factors of this are 1 and 7.
For something like the number 32, it is composite and not prime because it has the factors {1,2,4,8,16,32} and it leads to these three factor pairs: 1*32, 2*16, 4*8. This is one example showing why the answer isn't composite.
-----------
Let's say that p is the unknown prime we want to find. The factors of this are 1 and p. We're told that "one of the factors is twice the other factor", so that must mean p = 2*1 = 2. We can see that 2 is twice that of 1.
Answer:
this should be 132 units i hope this helps! :)
Step-by-step explanation:
so these figures are similar
we are given 3 side measurements on one, and 3 on the other
we know that side BA is 10 units, and that SR which is the same side, is 14 units
we can conclude that they added 4 units to this side
so with the other side lengths that we are given we can figure out what the length of the perimeter of RSTUV is
10 + 4 = 14
15 + 4 = 19
28 - 4 = 24
42 - 4 = 38
25 + 4 = 29
42 TU
28 UV
19 VR
14 SR
29 ST
add all the side together to get 132 units
