Answer:
$168
Step-by-step explanation:
1. x - 1/4x = 126
2. multiply each side by 4
3. 4x - x = 504
4. 3x = 504
5. divide each side by 3
6. x = 168
You have to use the formula to find the area of the triangle Remember,the area equation is b times h to the b divided by 2.Doing this will get you 600 m.
Hello this is my easy way to multiply with zeros.What you do is ignore the zero like its not even there next you multiply whats left so we multiply 3 x 4 and that is 12.next we add the zero and that's it.Hoped I Helped! :D
Answer: V= 4500m^3
Explanation:
V= length x width x height
V = 600 x 3 x 2.5
V = 600 x 7.5
V = 4500
