Just think of each face differently and find the area i cant rly see the shape...
Start with the parentheses first
4.6 -4.4+7.8 then calculate from left to right
= 0.2+7.8 = 8
Answer:
1) B) a = 14
2)D) x = -11
3)B) x = 8
4)A) 250 = 3c-20
5)D)8
6)B), C), D)
8)A) 14 months
9)Sarah = 40 years
Sarah = 5/4 x Tanya
40 = 5/4 x Tanya's age
Therefore Tanya's age is 32 years old
Hope this helps you!
