Answer:
there are 210 minutes in 3 and a half hours
Step-by-step explanation:
In order to simplify the expression (b+11)2b, we need to use the concept of distributive property.
Distributive property:
The distributive property of multiplication over addition can be used when you multiply a number by a sum.
![a(b+c)=a*b+a*c](https://tex.z-dn.net/?f=a%28b%2Bc%29%3Da%2Ab%2Ba%2Ac)
Our expression is:
2b(b+11)
Applying distributive property here :
![2b(b+11)=2b*b+2b*11](https://tex.z-dn.net/?f=2b%28b%2B11%29%3D2b%2Ab%2B2b%2A11)
![=2b^{2}+22b](https://tex.z-dn.net/?f=%3D2b%5E%7B2%7D%2B22b)
Answer: ![2b^{2}+22b](https://tex.z-dn.net/?f=2b%5E%7B2%7D%2B22b)

=648 cm2
Answer:
A) Because A and E are perpendicular therefore making B 90 degrees. D same for DBC
B) Same as A. for A
C) because they are perpendicular to eachother
D) Because they are the same angle they are equal to eachother
E) We assume that they are both 45 degrees thus making them equal to eachother
