14 ft First, find the unlabeled lengths 6-1=5 and 14-1 = 13 Find the perimeter by adding the lengths of the sides, 14 + 6 +13+1+1+5= 40 ft and 6x 14 To find the area, divide the figure into 2 rectangles, 1 x 1 Use the formula A =bxh to find the areas. Then, find the sum of the areas, 5 + 78= 83 sq ft. is this right?​

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