Answer:
D
Step-by-step explanation:
X is 21
z is the same as 111
y is 48
<em>30(30 - x) = 540 </em>
A = l w
<u><em>30(30 - x) = 540</em></u>
Box 2 has 3 times the volume of Box 1....
2
Its pretty easy math
solution
given a=1_9k and b=j+k
Now,ab=(1_9k)(j+k)
=1((j+k)-9k(j+k)
=j+k_9jk-9k^2
=k_9k^2+j_9jk
=k((1_9k)+j(1_9k)
=(1_9k)(k+k)
