Porfa ayuda pero rapido Determine las soluciones de las siguientes inecuaciones de segundo grado y
represéntelas en la recta numérica y en conjuntos:
a) 3 2 − 27 ≤ 0
b) ( − 3)(2 − 1) + ( − 3)(− + 5) ≤ 0
c) 2 + 12 + 35 > 0
d) 4( − 6/2) ≥ ( − 3/14 )
e) (2 + 5) 2 − (2 + 5)(5 − 4) < 0
f) 4 2 −1/ 3 [15 − 3(−1 + 2)] < 3/ 2 (9 − 2 − 6)

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

i think it will be 4feet long of what i comprehend
