Answer:
The value of x is 8 gallon.
Step-by-step explanation:
Given a table showing approximate conversion from gallons to liters.
Number of Gallons 2 4 x
Number of Liters 7.6 15.2 30.4
We are required to find value of x,
Given : 2 gallon is equal to 7.6 liters.
⇒ 1 liter is equal to liters. ........(1)
given, x gallon equal to 30.4 liters.
⇒ 1 liter is equal to liters. .........(2)
from (1) and (2),
⇒
Solving for x, we get,
⇒
⇒
Approximately x = 8
Thus, the value of x is 8 gallon.
Answer is x² + 2x + 5
<u>Step-by-step explanation:</u>
Step 1:
Add the two polynomials
⇒ (2x + 7) + (x² - 2) = 2x + 7 + x² - 2 = x² + 2x + 5
Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions
Step-by-step explanation: (x+2) = 0 only has one solution.
(x+2)*(x-4) = 0 has two solutions, -2 and 4
(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc
If "many" means more than three, then add another (x+XX) term. A quadratic equation generally has two solutions.

Step-by-step explanation:
One vertex is at point (2,3).
Go 1 unit to the left and 5 units up, then the second vertex will be at the point (1,8).
Go 5 units to the right and 1 unit up, then the third vertex will be at point (6,9).
Go 1 unit to the right and 5 units down, then the fourth vertex will be at point (7,4).
Go 5 units to the left and 1 unit down to get into the vertex (2,3).
Since you always move one unit in one direction and 5 units in another direction, obtained quadrilateral will be a square.
See attached diagram for details.
