I am stugling with algebra (because of zoom classes) and have multiple questions, please answer as many as you can. Thank you! 3x + 7 = 4x X=
x + 2 + 2x = x + 10 X=
x + 3x = x + x + 10 X=
2x + 3 + 3x = x + 11 X=
(oh and PLEASE explain this to me!)

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

In the diagram, the ratios of two pairs of corresponding sides are equal to prove that almn - axyz by the sas similarity theorem, it also needs to be shown that x 6 z un z zz un = 2x zləzz lezy
