Option 3. step 1.
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
So, to start answering this, lets recall the formula for a rectangles volume:
This formula is :
V=h*w*l
Lets plug in what we know, and solve for the missing variable.
We know that height(h) is 7.
We know that width(w) is 9.
We know that volume(V) is 378.
We are missing length(l)
So:
378=7*9*l
To find length(l), we must iscolate it.
To do this, we must get rid of the 7 and 9.
So lets start by dividing 378 by 9:
378/9=7*9/9*l
=
42=7*l
Now lets do the same thing with the 7 to iscolate l:
42/7=7/7*l
=
6=l
So our missing length(l) is 6.
Answer:
l = 6
Hope this helps!
Answer:
Step-by-step explanation:
Move 
to the denominator in 
using the negative exponent rule 
Answer:
x = 10
Step-by-step explanation:
We know x = 6
asked: x + 4
Plus it in =>
6 + 4
=> 10
The answer to this in simpler form is 2/5
