How do you find the answer for 3a-1? What's the answer? What's the equation you write down?

The question is not correct ma'am

It is impossible to know the solution of this expression unless you know how much a is worth or some information on the other side of the equation. If you don't know what I mean then I'll explain it a bit more. An equation is 2 expressions that are equal to each other but here I don't know anything about the other side of the equation. For example, an equation like this: 3a - 15= 6 is solvable because I know enough information to solve this.

3a - 15 + 15= 6 + 15

3a = 21

Therefore I can now find out what the answer is but your equation does not have enough information for it to be solved.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
