Answer:
x = 2
Step-by-step explanation:
BO = OD
they are apart of the same line segment with O as the midpoint of BD
since they're equal set equal and solve for x
7x + 4 = 18 subtract 4 from both sides
7x = 14 divide both sides by 7
x = 2

Answer:
the distance between the penguins and the fish tanks is 81 ft
Step-by-step explanation:
Let A is the point of whales
Let B is the point of Sharks
Let D is the point of Dophines
Let P is the point of penguins
Let F is the point of Fish tank
From a look at the photo, we can find some special properties that:
AB//PF
In triangle ABD and DPF we have
- ∠BAD=∠PFD(Alternate angles)
- ∠ADB=∠PDF(Vertically opposite angles)
By AA rule, ABD and DPF are similar to each other
Therefore, using the similarity property, we have:
=
So the distance between the penguins and the fish tanks is 81 ft
B. 12
Ex: 12 squared is 144
