The roots of the parabola is where the x-intercepts are so the answer is x=-1 and x= 5
DE + EF = DF
x - 2 + 6x + 4 = 8x - 2
7x + 2 = 8x - 2
2 + 2 = 8x - 7x
4 = x <===
thank me the answer is x=3.6
Answer:
Step-by-step explanation:
(a) A square has all the 4 sides being equal while a rectangle has four sides, with the opposite sides being parallel and the same length.
(b) The diagonals bisect the angles , the diagonals are perpendicular bisectors of each other
(c) A square has two pairs of parallel sides, four right angles, and all four sides are equal while the angles of a parallelogram are not right angles
(d) a rhombus can be a rectangle (if the angles of the rhombus are all 90 degrees), and a rectangle can be a rhombus (if the sides of the rectangle are all equal length). Opposite sides are parallel.
(e) a rhombus has two opposite internal angles of equal measure, a square has four right angles with equal measure
Mindi should have added the 8 and 9 to make the expression 17-9x
