I just know the greatest common factor is 2ab
But i don’t know if it is foil method but I still don’t know how to put it in that format
I'm not sure but
A) 3 out of 20
B) 11 out of 100
Divide distance by time:
10.5 inches / 3 seconds = 3.5 inches per second
Answer: 3.5 inches per second
* means multiply, sqrt=radical
expand
-10+sqrt2*8i-sqrt2*15+24i
group
(-10-sqrt2*15)+(sqrt2*8+24)i
not exactly sure though
