Answer:
The length of AB is 30 units.
Step-by-step explanation:
Given B is the midpoint of AC and D is the midpoint of CE.
BD = 3x, AE = 60 and AC = 5x + 10
we have to find the value of AB.
As B is the mid point of AC and D is the mid-point of CE.
By mid-point formula, the length of line joining the mid-points of two sides of triangle is half of the parallel side.
∴
⇒
⇒
As, B is the mid-point of AC
⇒
The length of AB is 30 units.

Answer:
26 units
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and reflection.
If a point A(x, y) is reflected across the y axis, the new point is A'(x, -y).
The reflection of the point (-2,-4) across the x axis gives (-2, 4) while the reflection of (3, -4) gives (3, 4)
The distance between (-2, -4) and (-2, 4) is the length while from (-2, -4) to (3, -4) is the breath. Hence:
Perimeter of rectangle = 2(length + breath) = 2(8 + 5) = 2(13) = 26 units
