-2(x-3)+5x+7=3(4-3x)+12x-9                         - problem
-2x+6+5x+7=3(4x-3x)+12x-9                        - distributive property
5x-2x+6+7=3(4x-3x)+12x-9                          -  combine like terms
3x+13=3(4x-3x)+12x-9                                   - combine like terms
3x+13=12x-9x+12x-9                                     - distributive property
3x+13=3x+12x-9                                            - combine like terms
3x+13=15x-9                                                  - combine like terms
13=12x-9                                                        - subtract 3x from both sides
22=12x                                                          - add 9 to both sides
x=0.5454

Please help me for the brainliest answer
7nadin3 [17]
The answer is 928cm. There are 5 sides. When you find the area of a triangle you multiply base times height then divide by two. But in this case there are two identical triangles so you don’t need to divide. 24x12=288. Then you find the area of the long sides. Multiple 25 and 10 and you get 250. There are two of those sides. Now the last thing to do is find the area of the bottom side. For that one you multiply 14 and 10 and get 140. Now you add all of that together and get 928cm.

What are the domain and range of the function f(x) = 3/4x + 5?
pantera1 [17]

Answer:

Domain = (-∞,∞)

Range = (-∞,∞)

This is a linear function.

So, if you were to graph this you'd know that it crosses the x and y axis and continues on forever without stopping.

in that case the domain and range are considered infinite on both axes.
