Lisa [10]

Answer:

see explanation

Given the following rectangle and circle, at what approximate value of x are the two areas equal? Show work and explain all step
suter [353]

Answer:

x ≈ 1.28

Step-by-step explanation:

I just took the exam:

Area of rectangle =(3x-1)(x+6), Area of circle = PI(x+1)^2. If you graph these and find where they intersect, you will get x ≈ 1.28.

I hope this helped! :)

Which points can be connected to draw a line of symmetry through this figure?
Alex Ar [27]

The symmetry line is passing through points F and E. Then the correct option is B.

<h3>What is reflectional symmetry?</h3>

Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly like the shape itself, then that shape is called to have reflectional symmetry.

Then the symmetry line is passing through points F and E. Because F and E are the mid-points of AD and BC.
