The complete question is as follows.
The equation a =
can be used to determine the area , <em>a</em>, of a trapezoid with height , h, and base lengths,
and
. Which are equivalent equations?
(a) 
(b) 
(c)
= 
(d) 
(e)
= h
Answer: (a)
; (d)
;
Step-by-step explanation: To determine
:
a = 
2a = (
)h


To determine h:
a = 
2a = 
= h
To determine 
a = 
2a = 


Checking the alternatives, you have that
and
= h, so alternatives <u>A</u> and <u>D</u> are correct.
Hello there!

Add 5x to both sides:

Add 14 to both sides:

Now divide both sides by 8:

In our last step, we will simplify 16/8:

Hope this helps!

Answer:
B
Step-by-step explanation:
B) because both result in the equation 8 x = 400, which simplifies to x = 50

Answer:
As far down/low as you can go.
Step-by-step explanation:
Usually used with upper and lower bounds it means that the "greatest decrease" you can go is 4.5 for example.
If that is what you meant then hope this helps :)
