P = 2(L + W)
L = W + 5
A = 4P + 2
P = 2(W + 5 + W)
P = 2(2W + 5)
P = 4W + 10
A = 4P + 2
A = 4(4W + 10) + 2
A = 16W + 42
A = L * W
A = W(W + 5)
A = W^2 + 5W
W^2 + 5W = 16W + 42
W^2 + 5W - 16W - 42 = 0
W^2 - 11W - 42 = 0
(W + 3)(W - 14) = 0
W - 14 = 0
W = 14 <==
L = W + 5
L = 14 + 5
L = 19 <==
P = 2(19 + 14)
P = 2(33)
P = 66
A = L * W
A = 19 * 14
A = 266
answer : length = 19, width = 14....perimeter = 66....area = 266

Answer:
Part A.) 70 pages each day
Part B.) Nora has already read 84 Pages, She has 196 pages remaining. Nora should choose OPTION 1 because it will take her 4 NIGHTS to finish it instead of 7 NIGHTS with OPTION 2
Step-by-step explanation:
A.) You need to find 25% of 280. In order to do so, you can convert 25% into a decimal by moving its decimal two places to the left. 25.0% is then changed to 0.25. Next, simply multiply 0.25 by 280 to get 70 pages per night
B.) First you need to get 30% of 280
Like above, you simply multiply the decimal value of 30% to 280; the decimal value of 30.0% is 0.3(move decimal two places left) and 0.3 * 280 = 84 pages. Nora has already read 30% of the book, 84 pages.
Next you subtract 84 from 280 to get the remaining pages left. 280 - 84 = 196 pages left.
Finally, you compare the two options.
25% of 196 = 0.25 * 196 = 49 pages each night
196 / 49 = 4 nights until Nora completes the book
28 pages a night
196/ 28 = 7 nights until Nora completes the book
Answer:
84
Step-by-step explanation:
The equation that models this situation is 1110 = 15x + 150 where x = cameras sold (note that this doesn't include the first 20 cameras, we'll add those on at the end). Let's solve for x!
1110 = 15x + 150
960 = 15x
x = 64 so the answer is 64 + 20 = 84 cameras.
Answer:
they all as a group will be doing 1/3 of the work. There are 4 robots.
how much will each individual robot be doing from the total work?
well, how many times does 4 go into 1/3?
