Step-by-step explanation:
I just answered that. how often did you put that in ?
Answer:6.7
Step-by-step explanation:
5t-17.2=16.3
5t=16.3+17.2
5t=33.5
5t/5t=33.5/5
t=6.7
The new perimeter would be 60. because the width and the height are doubled.
Answer:
9
Step-by-step explanation:
x didn't change in value, y changed by 9
the distance between the two points is 9
Answer:
unit
Step-by-step explanation:
Since Here Δ ABC is a isosceles triangle.
Also,
and
Thus, ∠ ADH = 90°
That is, Δ ADH is the right angle triangle.
In which, AD = a unit and HD = b unit
And, By the definition of Pythagoras theorem,

⇒ 
⇒ 
Since, the perimeter of a triangle = sum of the all sides of the triangle.
Therefore, perimeter of ΔADH = AD + DH + AH
=
unit
