Algebra ! show work ! annie is framing a photo with a length of 6 inches and a width of 4 inches. the distance from the edge of the photo to the edge of the frame is x inches. the combined area of the photo and frame is 63 square inches. a. write a quadratic function to find the distance from the edge of the photo to the edge of the frame. b. how wide are the photo and frame together?

The frame is a rectangle with a rectangle cut out of it. The area of the frame is 4*6=24 square inches. So the area of the big rectangle (frame and picture) is 48 square inches. (Draw a picture and it will help.) Let's call the width of the frame x. So the distance from the edge of the picture to the edge of the frame is x at any edge. So the equation is (6+2x)(4+2x)=48. Expand this and solve for x and you get x=-6,1. x is a distance, so it must be 1. So the frame is 1 inch wide.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

i can you with this question sweetie!
