Let us manually add the given numbers.
450
790
123
____
1363  
 
Therefore we see that the correct answer 1363 which is far
from what Jill got which is only 1163.
Therefore the answer is No, the sum should be 1363 (closer
to 1400).
 
        
                    
             
        
        
        
The room is 15yd × 10yd 
so 15×10=150 
the room is 150 square ft
        
                    
             
        
        
        
Answer:
2. Line MK is the perpendicular bisector of LN.
3. ML ≅ MP
4. ML ≅ MN
Step-by-step explanation:
To prove that ΔLMP ≅ ΔNMP by HL.
The second option or statement states that :
Line MK being the perpendicular bisector of LN then it will explain that angles PML and PMN are right angles. Thus, they are congruent.
Statement 3 and 4 says that 
ML, MP, and MN are congruent. Since ML is congruent to MP and MN both. Thus conclude that triangle ΔLMP ≅ ΔNMP by HL
Thus, the correct answer  - option 2, 3, and 4.
 
        
                    
             
        
        
        
False, bc when you plug in the x and y values the equation isnt true.
