7*100+2*1= 702
10+5*1= 15
702+15= 717
i hope that is really does help if it don't i am sorry
Answer:

Step-by-step explanation:
W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form
.
We know that vertex form of parabola in form
, where (h,k) in vertex of parabola.
Upon substituting coordinates of vertex, we will get:

To find the value of a, we will substitute coordinates of point (0, -1) as:







Therefore, our required equation would be
.
Each person received one quarter, which can be written as 1/4 or 0.25.
" the quotient " means divide
(x/3) - 4 <== ur expression
The sides of an equilateral triangle are equal length, so ...
GH = FH
3x-9 = 2x-2
x = 7 . . . . . . . . add 9-2x
Then the side lengths are
FG = x+5
FG = 7 +5 = 12
x = 7
FG = GH = FH = 12
