Evaluate the expression 2^x- x^22 x −x 2 2, start superscript, x, end superscript, minus, x, squared for x=5x=5x, equals, 5.

Which statement accurately explains whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure acb onto itself? a coordinate plane with figure acb with point a at 1, 1, c at 3, 4 and b at 5, 1 yes, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) yes, a″c″b′ is located at a″(1, 1), c″(3, 4), and b″(5, 1) no, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) no, a″c″b″ is located at a″(1, 1), c″(3, 4), and b″(5, 1)

Idon't get undoing if its pass adding and subtracting so can someone ? x-2 over 5 = 18

Solve the equation for b: a= (1/2)(b)(h)
