Show that the vectors a = 3i, b = 4 j and c = 3 i + 4 j form a right angled triangle.

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

Points j and k plotted on the coordinate grid are two vertices of rectangle jklm rectangle jklm has an area of 7 square units point j is located at 2,1 and point k is located at -5,1 each vertex of the rectangle is located at a point that has integer coordinates. what is the perimeter of rectangle jklm? (need answer asap)

The sequence [tex]a_{n}[/tex] = 5n + 3 is the same as the sequence [tex]a_{1} = 8, a_{n} = a_{n-1} +5[/tex]
