Answer:
The difference is 40, 
Step-by-step explanation:
Complementary angles , x+y =90
so we know angle 1, we call it  3x and angle 2 we call it y= 3x+10
so 3x +10= 90-x
4x=100
x=25
 angle 1= 3(25) - 10
y= 65
65-25= 40

Answer:
1, 17, 33, 49
Step-by-step explanation:
given the first term is 1 then the next 3 terms are
1 + d, 1 + 2d, 1 + 3d ( d is the common difference )
the sum of the first 4 terms is 100 , then
1 + 1 + d + 1 + 2d + 1 + 3d = 100 , that is
4 + 6d = 100 ( subtract 4 from both sides )
6d = 96 ( divide both sides by 6 )
d = 16
1 + d = 1 + 16 = 17
1 + 2d = 1 + 2(16) = 1 + 32 = 33
1 + 3d = 1 + 3(16) = 1 + 48 = 49
the first 4 terms are
1, 17, 33, 49
 
        
                    
             
        
        
        
Your answer is right
3x^2 + 13x + 4
