Answer:
B. (b+3c)+(b+3c)
C. 2(b)+2(3c)
Step-by-step explanation:
we have

Distribute the number 2

Verify each case
case A) 3(b+2c)
distribute the number 3


therefore
Choice A is not equivalent to the given expression
case B) (b+3c)+(b+3c)
Combine like terms


therefore
Choice B is equivalent to the given expression
case C) 2(b)+2(3c)
Multiply both terns by 2


therefore
Choice C is equivalent to the given expression
Well x is an obtuse angle
but the angle e,f,g is an acute angle
X = 12
18/24 = .75
16 x .75 = 12
A mixed number that is equivalent to 16/3 is
5 1/3
The line will remain unchanged because you are just and only dilating the rectangle. I hope this helps :).-
