Answer:
dư 0... 7^300 chia 7 đc 7^299 mà
1 yd = 36 in; 20 ft 8 in = 248 in;
We will use a proportion:
36 : 24 = x : 248
24 x = 36 * 248
24 x = 8,928
x = 8,928 : 24 = 372
Answer: C ) 372 in
Answer:

Step-by-step explanation:
We know that the vertex(lowest point) of
is
.
By inspection, we can see that the vertex of the graph is
.
So, the lowest point of
is
, which means 
-converting to a common denominator
The terms -c of the left side was converted to -4ac/4a to have the same denominator of b^2/4a.
