X + 25 - 10. 25-10 is 15 so you had 15 after class. You must had 8 sheets of paper because 8+25=33. 33-15 is 18. So, you had 8 sheets of paper before class. Hope this helps!
Let the width = w.
Then the length is 3w - 5.
The area = LW = 28
w(3w - 5) = 28
3w^2 - 5w = 28
3w^2 - 5w - 28 = 0
(3w + 7)(w - 4) = 0
3w + 7 = 0 or w - 4 = 0
w = -7/3 or w = 4
The width of a rectangle cannot be a negative number, so we discard w = -7/3.
The width is 4 ft.
The length is 3w - 5 = 3(4) - 5 = 12 - 5 = 7
The length is 7 ft
Answer: The dimensions are length 7 ft and width 4 ft.
Answer:
(0, -3)
(-1, -10)
Step-by-step explanation:
363 rounded to the nearest tenth is 360
the greatest possible error for meters is 1/2 the increments
since 18.9 is to the tenths place
1/2 x 1/10 = 0.05
so greatest possible error for 18.9 is 0.05m
