Answer:
4a(5a + 1)
Step-by-step explanation:
Given
20a² + 4a ← factor out 4a from each term
= 4a(5a + 1)
Subtract second y from first y and divide that by second x from first x
1-2=-1
3- -5=3+5= 8
so, -1/8
this is your m= -1/8
now pick one of the points and add it to your point intercept form (I'm picking (3,1))
y-1= -1/8 (x-3)
y-1= -1/8x - (-1/8×3)
y-1= -1/8x +3/8
y= -1/8x +3/8+1
y= -1/8x +11/8
Answer:95.7 or 8.7
Step-by-step explanation:
It would be between 11 and 12 because 11 times 11 = 121 and that is smaller than 123. Also 12 times 12 is 144 and 12 a whole number.
I think B, but not 100% sure.
