Answer:
s=Q/Rt - 1/t
Step-by-step explanation:
46 = f/10 - (-43)
46 = f/10 + 43
f/10 = 46 - 43
f/10 = 3
f = 3*10
f = 30
It's D. Slopes are the same, because if you divide opposite and adjacent side of both triangles, you get the same result. Count the squares, for the smaller triangle it's 2/2=1 and for the bigger one it's 4/4=1.
Esitmate:
9 /3 = 3
and
8-4 = 4
so it would be 3x10^4
answer is C
