in simplest form
Take into account that x represents the number of decades after 1950. Moreover, consider that -0.5x is a decrease in the values of y, each decade.
Then, you can conclude that each decade, that is, every 10 years, the shoreline reduces 0.5 feet.
Hnece, you have:
The shoreline is reduced by 0.5 foot every 10 years
Answer:
34
Step-by-step explanation:
Centimetres by square on the grid. So 12 squares +12+5 squares +5= 34
Perimeter (P) = 2L + 2w
68 = 2L + 2w
68 - 2L = 2w
2(34 - L) = 2(w)
34 - L = w
********************
Area (A) = L * w
240 = L (34 - L)
240 = 34L - L²
L² - 34L + 240 = 0
(L - 10)(L - 24) = 0
L = 10 or L = 24
w = 34 - L = 34 - 10 = 24 or w = 34 - 24 = 10
Answer: width = 10, length = 24 assuming length is bigger than the width
