the measurements of a photo and it's frame are shown in the diagram. Write a polynomial that represents the width of the photo.
suter [353]

Answer:

The width of the photo is 4w^2+6w+4.

Step-by-step explanation:

From the given figure it is notices that the total width of the frame is

6w^2+8

The photo is covered by a frame border and the width of the border is

w^2-3w+2

To find the width of the photo we have to subtract the width of upper frame border and lower frame border from the total width of frame.

Width of the photo is

\text{Width of the photo}=\text{Width of the frame}-2(\text{Width of the frame border})

\text{Width of the photo}=6w^2+8-2(w^2-3w+2)

\text{Width of the photo}=6w^2+8-2w^2+6w-4

\text{Width of the photo}=4w^2+6w+4

Therefore the width of the photo is 4w^2+6w+4.

Lucy's weekly income is $70. she budgets $40 for movies and food and saves the of her income. how much money will she save in 6
vlada-n [284]
Weekly income = 70...she budgets 40 for movies and food.....70 - 40 = 30...that leaves 30 per week that she saves.

1 month = 4 weeks....so 6 months = (6 * 4) = 24 weeks

24 weeks....saving 30 per week = (24 * 30) = $ 720 <===
