Answer:
1. 
2. 
3. 
4. 
Step-by-step explanation:
D for the same reason percents
If the bases ar same, assume exponents are same
if
x^z=x^m
assume z=m
so
base is both 7 therefor
3x+5=1-x
solve
add x
4x+5=1
minus 5
4x=-4
divide 4
x=-1
The sum of the two sides of the triangle must be greater than the third side, so
5<x<41 is the answer
