Answer:
67
Step-by-step explanation:
Subsitute both given values into the equation then continue to simplify the equation
3(4(-2)+5(3)) -2(7(-2)-3(3))
3(-8+15) -2(-14-9)
3(7) -2(-23)
21 +46
67
Answer:
number 9 is c.
im not really sure what 10 is
Answer:

Step-by-step explanation:




One
The sum of two rational numbers is always rational. sqrt(9) + sqrt(25) = 3 + 5 which is rational. sqrt(16/100) = 4/10 = 2/5 is also rational. 3/28 is rational as well.
Two
Those are irrational. sqrt(10) + pi = ???? You cannot reduce this to any kind of fraction. Two irrationals always give a rational.
Three
The irrational number controls the answer. 10 + sqrt(5) is irrational. The 10 is OK. It is raional, but sqrt(5) is not a rational number.
The answer is four .......
