Answer:

<h2><em>B. (b+3c)+(b+3c) </em></h2><h2><em>C. </em><em>2(b)+2(3c)</em></h2>

Step-by-step explanation:

Given this expression 2(b+3c), its equivalent expression is derived by simply opening up the bracket as shown below;

Open the parenthesis by multiplying the constant outside the bracket with all the variables in parenthesis.

= 2(b+3c)

=  2(b)+ 2(3c)

= 2b +2*3*c

= 2b +6c

It can also be written as sum of b+3c in 2 places i.e (b+3c)+(b+3c) because multiplying the function b+3c by 2 means we are to add the function by itself in two places.

<em>Hence the equivalent expression are (b+3c)+(b+3c) and 2(b)+2(3c) or 2b+6c</em>

Answer:

25 ft

Step-by-step explanation:

The 2 triangles are similar hence the ratios of corresponding sides are equal, that is

\frac{x}{5} = \frac{40}{8} = 5

multiply both sides by 5

x = 5 × 5 = 25

The height of the tree is 25 ft
