Answer:
The train engine is <u>15 centimeters</u> long.
Step-by-step explanation:
The train car length doesn't matter. All you need to do is subtract 32 cm from the total length, 47 cm.
47-32=15 cm
The train engine is 15cm long.
if you are only counting the adults then 4 times i children to then 10 time
By using x-method we got that factorization is (x+5)(x-5)
<h3>What is factorization ?</h3>
factorization is writing a expression as a product of several factors.
So Given polynomial is
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
By using x-method we got that factorization is (x+5)(x-5)
