I'm pretty sure it would be y=2x+9
I think it represents the height hope that helps:)
Answer:
AC ≈ 9,7sm
Step-by-step explanation:
AB=7 One side of a right triangle
BC=12 Hypotenuse of a right triangle
AC=?=x The other side of a right triangle
x²+7²=12²
x²=144-49
x²=95
x=√(95) ≈ 9,7
AC ≈ 9,7sm
Scientific notation:
8.41 x 10^7
expanded form:
84100000
