Well you find how much the error was and divide it by the amount he predicted.
30/230= 0.13 0.13=13%
I don't know if this will help but the 2 on the right are not parallelograms there
"3d"
X + 2y = 2
If you need an explanation, let me know.
Answer:
2x=-1 or x=-0.5
Step-by-step explanation:
4x-6=10x-3 (-4x)
-6=6x-3 (+3)
-3=6x (divide by 3)
-1=2x
4a^3b^5 - 16a^5b^2 + 12a^2b^3 =
4a^2b^2 (ab^3 - 4a^3 + 3b) <==
