Answer:
At least two of the opposite sides must be parallel.
Step-by-step explanation:
In the picture below, the segment AB must be parallel to the segment DC so that the figure can be called a trapezoid.
Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to
in 
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is 


Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:

x° = - 3.5
x° = 
Thus per hour; the temperature falls at the rate of
Answer: -77
Step-by-step explanation:
(-7(3)^1/2)(11(10)^1/2)=
-7*11*(3)^1/2 * (10)^1/2=
-77*(3*10)^1/2=
-77(30)^1/2=-77
Step-by-step explanation:
22x+7= -15
22x= -15 -7
22x = -22
x= <u>-</u><u>2</u><u>2</u>
22
x= -1
Hope this helps you dear !
Have a great day :)
