Answer:
x=  0.5
 or x=  -1.5
Step-by-step explanation:
Let's solve your equation step-by-step. 
4x2+4x−3=0 
Step 1: Factor left side of equation.
 (2x−1)(2x+3)=0 
Step 2: Set factors equal to 0.
 2x−1=0 or 2x+3=0 
x= 1/2 or x= −3/2
 
        
             
        
        
        
Answer:
x = 110°
Step-by-step explanation:
The sum of the interior angles in a quadrilateral is 360°. This means:
x + x + x - 30 + 1/2x + 5 = 360° - we can simplify this
3 1/2x - 25 = 360° - now add 25 to both sides
3 1/2x = 385 - finally divide both sides by 3 1/2
x = 385 ÷ 3.5 = 110
x = 110°
Hope this helps!
