Distribute

(2/5) (a) + (2/5) (b) + (3/5)(a) +(3/5)(c)

= 2/5a+2/5b+3/5a+3/5c

Combine like terms

2/5 a + 2/5 b + 3/5 a + 3/5 c

= ( 2/5 a + 3/5 a ) + ( 2/5 b) +(3/5 c)

= a + 2/5 b +3/5 c


I hope that's help !

Naya [18.7K]
For this case, the first thing to do is find the scale factor.
 Using the measure of height we have:
 k = (360) / (18 * (1/12))
 k = 240
 Thus, the length of the building is:
 (14 * (1/12)) * (240) = 280 feet
 Answer:
 
The lenght of the real building is:

Find the distance between the point (3,1) and the line with the equation y=2x-5
True [87]

Answer:

B:  0

Step-by-step explanation:

Note that (3, 1) satisfies the equation y = 2x - 5:

1 = 2(3) - 5

1  =  6 -5  = 1

Therefore, the distance between this point and this line is zero.

B is the correct answer.
