What is the solution to the equation 3 (2 x + 5) = 3 x + 4 x?

a)x = 0

b)x = 4

c)x = 5

d)x = 15

Step-by-step explanation:

Step 1: Simplifying the equation we can find the value of x.

Step 2: Multiply 3 with

x

Step 3: Adding 3x with 4x, which gives the equation

Step 4: Subtracting both sides of the equation by 6x

Thus, the solution to the equation  is  

answer: '

the distance between points l and m

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
