Area of rhombus = 0.5 x D1 x D2
Thus,
Area = 0.5 x 30 x 18
= 270 units ^2
Answer:
4(2k-1)
Step-by-step explanation:
Answer:
--- Vertex
--- Axis of symmetry
Step-by-step explanation:
Given

Solving (a): The vertex
For an equation written in

The vertex is:

By comparison:
and 

So, the vertex is:

Solving (b): The axis of symmetry
For an equation written in

The axis of symmetry is:
x = h
In (a):

So:

Hello,
y=x²-10x+7=x²-2*5x+25-25+7=(x-5)²-18
================================
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
