Answer:
x=3
Step-by-step explanation:
15 – 2x=3x
Add 2x to each side
15 – 2x+2x=3x+2x
15 = 5x
Divide each side by 5
15/5 = 5x/5
3 =x
Answer:
There is no solution because the graphs do not intersect
Step-by-step explanation:
Both of theses equations do intersect with one another when graphed. In conclusion, there is no solution.
The formula of a volume of a cuboid:

l - length
w - width
h - height
We have:
l = (x + 4) cm
w = (x + 1) cm
h = 3 cm
Substitute:
<em>use distributive property</em>


<em>combine like terms</em>

Answer:
5
the right answer is 5......
