Answer:
Step-by-step explanation:
the expression we have is:

To find an equivalent expression, it would be helpful to express 1/3 so that it has a 12 in the denominator:

so we substitute this:

and now we have 1/12 in both terms :

so we can factor it (we take it out of each term: in the first we are left with -x and in the second with -4):
the equivalent expression is:
The answer is :23
B:34
C:56
I think 11 is yes, if the parent is 40 and the child is 20. (and they had kids when they were young) 12 is yes, if the parent is 30 and the child is 10. 13 is yes, if the parent is 60 and the child is 40. unlikely though, but who cares. 14 is no, the parent would have been really young when they gave birth to the child. like 10.
Its rational
Square root of 1.69 is 1.3 which is rational ( 1.3 = 13/10)
For both complementary and supplementary angle...” No. For both complementary and supplementary angles, you can only have 2 angles and both of them must have positive measure. 1 or 3 or 4 angles can't be complementary or supplementary.
