Answer:
Area of ABD = 9/2 or 4.5cm^2
Step-by-step explanation:
Area of triangle = 

plug-in ABD


Area of ABD = 9/2 or 4.5cm^2
 
        
             
        
        
        
1 pound is 16 ounces
32 ounces is 32 ÷ 16 = 2 pounds
1 pound of Botcoil ⇒ 1.5
2 pounds = 1.5 × 2 = 3
 
        
             
        
        
        
This is unreadable try submitting a more clear picture. i can bairly read the first problem i think it says 8(3x+4)=2(17x????)
        
             
        
        
        
Firstly you need to to reduce to a common denominator by multiplYing the whole fraction. This way you have to multiply 4/5 by 2 (both numerator and denominator). so 4/5 = 8/10. And now you have 8/10 and 9/10. You compare only numerators. This way you have 8/10 <9/10. Same goes for 2/3 and 5/8. Only here you need to multiply both fractions. The common denominator here is 24. So you have to multiply 2/3 by 8 and 5/8 by 3. You now have to compare 16/24 and 15/24. 16/24>15/24.
        
             
        
        
        
407 over 5 but it also has to be simplified
