One side of triangle is 7 more than 2 times the shortest side. the third side is 15 centimeters more than the shortest side. the perimeter is 82. find all three sides.

12. decide whether each statement is always true, sometimes true, or never true. a. when corresponding points of an original figure and its reflection are connected, the resulting segments are all perpendicular to the line of reflection. b. when a point is reflected over a horizontal line, the y-coordinate of the point stays the same. answer both questions and explain

15 point ! ~ see if you know the answer to both you!

Multiply and simplify. 2x^2 y^3 z^2 · 4xy^4 x^2 i will mark you brainliest if right. show how you got the answer, !
