Plug x = 3 into the first piece to get
2(x+1) = 2*(3+1) = 2*4 = 8
Do the same for the last piece
x^2 - 1 = 3^2 - 1 = 9-1 = 8
So as we approach x = 3 from either the left or right side, the limiting value is 8
The final answer is 8
Answer:
D. 66 degrees Fahrenheit
Step-by-step explanation:
6 hours after 6 p.m. the temperature will have dropped 6×4 °F = 24 °F. When it drops that amount from 90 °F, it will be ...
90 °F -24 °F = 66 °F . . . . temperature at midnight
Answer:
Step-by-step explanation:
Volume = length × width × height
Volume of green box = 5 ft × 3.5 ft × 6 ft

Volume of orange box = 4 ft × 5 ft × 6.5 ft
= 130 ft³
The orange box has greater volume.

Answer:
11
Step-by-step explanation:
Given
x² - 7x + 10 = 28 ( subtract 28 from both sides )
x² - 7x - 18 = 0 ← in standard form
(x - 9)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 = 0 ⇒ x = 9
x + 2 = 0 ⇒ x = - 2
The distance between the solutions is
| 9 - (- 2) | = | 11 = 11 units
