Answer:
12
Step-by-step explanation:
12 IS THE ANSWER
PR = 12
P-----------Q-----------R----------S
ratio
4:2:1
PS = 14
add the ration = 4 + 2 + 1 = 7
14 / 7 = 2
PQ at 4 x 2 = 8
QR at 2 x 2 = 4
RS at 1 x 2 = 2
------------
14
PR = PQ + QR
PR = 8 + 4
x>-2 and x<5
-2 <x<5
We have open circles at -2 and 5 and are between the two numbers so we have and AND statement. It can be written either
or
its a or e
