Not 100% sure but i think its A
Step-by-step explanation:
Y2 - y1 1
--------- this equals - -----
x2 - x1 32
Answer:
Subtract 80 from 83 . The result of division of 8310 is 8 with a remainder of 3 .
So in this case, the depth is measured from the bottom up
0 is the bottom of the sea
a submarine can't go above the water
so
0≤d≤depth of ocean

Answer:
82 units
Step-by-step explanation:
From the image, we can see that the 2 triangles are similar triangles.
Thus:
BC = EF
BD = EG
CD = FG
Now, BD = 4x - 9 and EG = 2x + 15
Thus;
4x - 9 = 2x + 15
4x - 2x = 15 + 9
2x = 24
x = 24/2
x = 12
Thus, in triangle EFG where EG = 2x + 15, then EG = 2(12) + 15 = 39
Also, EF = BC = 17
FG = 26
Thus, perimeter of triangle EFG is;
P = 26 + 17 + 39
P = 82 units
