Answer:
The first step is A. Subtraction
The second steep is D. Division
Step-by-step explanation:
The first step was done in other to remove the constant at one end of the equality that was with the variable, it was done in order to eradicate the constant and isolate the variable to make the equation easier to solve.
The second step was done in order to remove the coefficient of the variable so as the variable to be on it's own as x alone.
These two steps were just followed in order to find the value of the variable.
Answer:
the Answer is 3x+12)+X=180
You can solve this problem by using the Gauss method. The Gauss method is a method where you can add the first and last numbers together, and then multiply by how many times that appears. Here, the sum of the first and last number is -11. In this sequence, it would appear ten times (since there are ten terms and the terms are used twice in every eleven). -11 * 5 is -55, so that means the answer to this question is -55.
81 square inches
9*9*9=729
729/9(height of cube)=81(length and width of cube=area of cube)
