Hello!
You find the area of a rectangle by the equation A = lw
A is area
l is length
w is width
Put in the values you know
180 = 3x * 6
Now you solve it algebraically
Divide both sides by 6
30 = 3x
Divide both sides by 3
10 = x
The answer is 10in
Hope this helps!
Answer: Decrease
Step-by-step explanation:
Answer:
x=24
Step-by-step explanation:
8x-13 = 7x+11; (because it's a rectangle)
8x - 7x = 11 + 13; (moving xs to one side, the rest to the other)
x = 24
Answer:

Step-by-step explanation:
solving for dy/dx
multiply the equation out to remove parentheses

now differentiating in terms of x (
)

isolating dy/dx to one side



As long as
(or whichever function appears in the denominator) does not approach 0 as
,

In this case,

so the answer is B.
