Expand and simplify 3(x-2)+2(4x-1)

Answers

The required simplified solution of the given expression is 11x -8.

Given that,
To determine the simplified expression that is equivalent to the 3(x-2)+2(4x-1).

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
3(x-2)+2(4x-1)
Applying the distributive law in order to multiply the 3 and 4 in the respective parenthesis.
= 3x - 6 + 8x - 2
= 11x - 8

Thus, the required simplified solution of the given expression is 11x -8.

Which expression can be used to find 52% of 230?A. 230/ 0.52

B. 0.52 • 230

C. 52 • 230 • 100

D. 230/52

Answers

Answer:

B) 0.52 * 230

Step-by-step explanation:

52% of 230 = 52% *  230

                    (52)/(100)*230\n\n\n=0.52 * 230

   

Answer: b

Step-by-step explanation:

We can state that :

  • 230⇒100 percent

        x⇒52 percent

so x=( 230*52)/100

       =230*0.52

What is the volume of the shape

Answers

the answer to this question would be D or 1512.
to solve this question, you find the volume of each prism. 
to find volume, you do length times width times height.
the top prism would be 15 times 12 times 6 which would be 1080
the bottom prism would be 6 times 12 times 6 which would be 432.
you add the volumes of the two prism or 1080+432= 1512.

hope this helps! :)
