The answer would be $2.00 because .43*5 = 2.15 and 2.00 is the closest
There's a 30 coefficient on the first and no coefficient (i.e. a 1) on the second. So the GCF of the constant part is GCF(30,1)=1.
Similarly, 
because both have 
as a factor.
because both have 
as a factor.
Now that we see how the bits work it's not too hard to read these off:
Answer:
8
Step-by-step explanation:
Sea el número x El cuadrado será x ^ 2
Entonces la suma será; x ^ 2 + x = 72 x ^ 2 + x-72 = 0
x ^ 2 + 9x-8x-72 = 0
x (x + 9) -8 (x + 9) = 0
(x + 9) (x-8) x = 8 o -9
Como solo estamos considerando números naturales, la respuesta correcta es 8
12 and 14
12^2=144
14^2=196
144+196=340
