The answer is 8. This is because when you substitute 8 with “a” you then solve the problem to see if it is equal to the answer. -4+8=4... -4+4=0 so that is wrong and -4+O=-4 which is also incorrect.
Im pretty sure it would be doubling the length of each side

Step-by-step explanation:
Answer: A is 36.82%. B is 35.5%
Step-by-step explanation: For manufacturer A 22/19 chian discount simply means 22% discount followed by 19% discount.
Therefore we have 100-22= 78 and 100-19=81.
The final price would be 0.78*0.81=0.6318
Therefore discount would be
1 - 0.6318=0.3682
Hence, percentage discount would be 0.3682*100%=36.82%.
For manufacturer B 25/14 chian discount means 25% discount followed by 14% discount. So we have 100-25=75% and 100-14= 86%
Final price would be 0.86*.75=0.645.
Discount= 1 - 0.645= 0.355.
Percentage discount would be 0.355*100%=35.5%.
