3(2x + 5)= 4 (c-3) I know how to solve it but can someone explain it.
Nezavi [6.7K]

Answer:

3x×2c+1

Step-by-step explanation:

6x+15 =4c-12

\frac{6x + 15}{4c - 12}  =  \frac{4c - 12}{4c - 12}

\frac{6x + 15}{4c - 12}

\frac{3x  + 5}{2c - 4}

3x + 5 \div 2c - 4

3x  \times 2c + 5 - 4

3x \times 2c + 1

Distance on graph
Mnenie [13.5K]
The graph can be divided into two shapes. A rectangle and a right triangle.

The distance that the rover will cover if it completes one circuit can be computed using the Pythagorean theorem and adding the sides of the rectangle.

Rectangle:
Width = 4 - 2 = 2 meters 
Length = 11 - 2 = 9 meters

Triangle = 16 - 2 = 14 ; 14 - 2 = 12 meters  (this is the short leg)
long leg of the triangle = length of the rectangle = 9 meters.

12² + 9² = c²
144 + 81 = c² 
225 = c² 
√225 = √c²
15 = c

Point A to B = 4 - 2 = 2 meters
Point B to C = 15 meters
Point C to D = 16 - 2 = 14 meters
Point D to A = 11 - 2 = 9 meters

Total distance traveled = 2 + 15 + 14 + 9 = 40 meters.
