X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
The first question is square or rectangle
I would say that the answer is: A translation of 4 units up, followed by a reflection over the y-axis, followed by a rotation of 90 degrees counterclockwise around the point shown on the figure.
Its - 3/2 if you need to know how I solved it, lemme know :)
