Answer:
1 is A. 2 is no. 3 is d. 4 is d. 5 is A
Explanation:
the first 1 u have to: 3x+4=-12 then 3x=-16 then x=-16/3
2: no because they aren't proportionate.
3: it isn't positive so it isnt a. the number on the left has to be between 1 to 10 so it can't be c and it obviously isnt b so the answer is d
4: a and b are rational due to the face that they are: a/b and c is rational because the square root of 169 is 13 therefore it is d.
5: a^2+b^2=c^2 a^2= 121. b=17/2 and b^2= 289/16. . i believe it is A
