First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!
        
                    
             
        
        
        
The answer should be 103. Because the interior angles of all triangles add up to 180 degrees, you can just add together the two known interior angles; subtract them from 180; and then find the supplement.
        
                    
             
        
        
        
Height = x (This is given) 
Length = 5x
Width = 6x 
Volume = length × width × height 
The equation will be: (5x)(6x)(x) = 1920 
simplify: 
30x² × (x) = 1920 
30x³ = 1920 
Divide both sides by 30 
x³= 64 
x = ∛64 
x= 4 
If x = height, then, the height is 4cm 
5x = length 
20cm = length 
6x = width 
24cm = width 
 
        
             
        
        
        
This is a polygon with vertices on the lattice.  Let's use Pick's Theorem,
A = (1/2) B + I - 1
where A is the area, B is the number of lattice points on the boundary and I is the number of lattice points in the interior.
In addition to the 3 vertices there are 3 more boundary points on UV and 6 more on WV, none on UV, B=3+3+6=12.   In the interior I count I=9 lattice points.
A = (1/2) 12 + 9 - 1 = 14
Answer: 14
Obviously they just want us to say this is a right triangle, so the legs are altitude and base,
A = (1/2) b h (1/2) |UW| |WV| = (1/2) (4) (7) = 14
That checks.
