Answer:
x=4
Step-by-step explanation:
21x+6+90=180
First, we need to subtract the numbers.
21x=180-90-6
21x=84
Now, we need to find the value for 1x, so divide the whole equation by 21
84/21
21/21
x=4
Hope this helps!
Answer:
n^2+2n+1
Step-by-step explanation:
-2-8-18-32-50
difference=-6-10-14-18
common differences=-4-4-4-4-4
-2-8-18-32-50
n^2=1,4,9,16,25
minus it
=-1,-4,-9,-16,-25
differences 2,5,7,9
common differences=2
2,4,6,8
so 2n+1
so the answer is n^2+2n+1
