Answer:
It is a factor.
Step-by-step explanation:
its definitely a factor
rule: put (x-2)=0
so x = 2
now put this 2 in the equation as x

which equals to 0, as a result its a factor
you can check the sum in the calculator by yourself
hope it helps.
Answer:
y = 90 meters.
Step-by-step explanation:
It is given in the figure that we have two triangles triangle A and triangle B are similar.
So,
.......... (1)
So, the ratio of the corresponding sides of two similar triangles remain same.
Now, x = 75 meters, n = 30 meters and m = 25 meters are given we have to find the value of y.
So, from relation (1), we have
⇒ y = 90 meters. (Answer)
A2= 1
a3=-3
a4=-7
the common difference is -4
Answer:
second one
Step-by-step explanation:
Because when you try to remove the brackets then you should multiply coefficient of x and coefficient of y by 2
So it will be 2x+18y
2*9=18
