Write an algebraic expression to find the PERIMETER of a rectangle with a length of 4x-5 and a width of 7. *Hint: draw yourself a rectangle, and label all 4 sides* *Make sure your expression is simplified, and in order, don't type any spaces.

Factor this polynomial completely x^2-64

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.

Which of the following exponential functions goes through the points (1, 6) and (2, 12)? f(x) = 3(2)x f(x) = 2(3)x f(x) = 3(2)−x f(x) = 2(3)−x
