It will be D. because you have to add the like terms which is 13 + 5 which will be 18 and so 10p doesn't have no like terms it just stays the same so it will be 10p+18
        
             
        
        
        
Area of rectangle = l × b
l = 70cm
b = 8cm
Area = 70 × 8 = 560cm²
Area of rectangle = l × b
l = 78cm
b = 15cm
Area = 78 × 75 = 1170cm²
 
        
                    
             
        
        
        
The answer is c because 
1) d is wrong because if the question give 8.78
 baru lah answer dia 8.8 mesti lebih dari 5 baru tambah 1 di depan
        
             
        
        
        
Question:
Find the value of the letter in each of the following and give reasons for the steps involved:
1 2 A
+ 6 A B = 
A 0 9
Answer:
128 + 681 =  809
Step-by-step explanation:
Here, let's use the general form of numbers where any  letter must represent one value and each digit must be represented by just one letter. 
Take the following:
A = 8
B = 1
Thus, A +B = 8 + 1 = 9
Also add:
8 + 2 = 10
In general form, tens digit is zero and the 1 is carried over. 
I.e, A = 1 + 6 + 1 = 8
We can now see that, 
A = 8
B = 1
Therefore, 
1 2 A
+ 6 A B = 
A 0 9
Will be written as:
128 + 681 =  809
