c and b are your answers
Answer:
b. 3b+b
c.2(2b)
Step-by-step explanation:
Option a is
b+2(b+2b) = b+2(3b) Adding the like terms b and 2b
=b+6b
=7b
Option b is :
3b+b = 4b (Like terms can be added)
Option c is
2(2b) = 4b. [ 2x2=4]
OPtions b and c both equal 4b.
1kg=1000g
Thus, 22kg=22000g
A for a box, the surface area is given by:
6l², where l is the length of one side.
If the side is increased 10 times,
6(10l)²
=100 x6l²
The surface area increases 100 times. Thus, the new surface area is
272 * 100
= 27,200 sq in
