Answer: J
Step-by-step explanation:
x=8, so substitute and Length=12 Width=9
Answer:
Step-by-step explanation:
Height doubles at every 30 seconds, so let's call n how many times it happens, and the t the total time:
n = t/30
If the height doubles one time, it is multiplied by 2, if it doubles 2 times, it's multiplied by 2², for n times, it is multiplied by 2ⁿ, so for an initial height equal to 3:

a^2 + b^2 = c^2
Let the length of the ladder be x.
One side is x - 16.
The other side is x - 8.
</span><span>(x-16)^2 + (x-8)^2 = x^2

x^2 - 32x + 256 + <span>x^2- 16 x+64 = x^2
x^2 - 48 x + 320 = 0
( x- 40 ) (x-8) = 0
x = 40 or x= 8
we discard the second so x = 40
