Step-by-step explanation:</h3>
<u>How can </u><u>we</u><u> factor 5x^2 + 26x - 24 = 0 using the completing the square </u><u>method?</u>
Let's solve your equation step-by-step.

First, add 24 to both sides.
Since the coefficient of 5x² is 5, divide both sides by 5.
The coefficient of 26/5x is 26/5. So, let b=26/5.
Then we need to add (b/2)²=169/25 to both sides to complete the square.
Add 169/25 to both sides.
Factor the left side.
Take square root.
Then, add (-13)/5 to both sides.

If you work backwards, she had 24 before going to the movies. This is 3/5 of what she had originally. Use this to find 1/5 the but dividing 24 by 4 = 8 then multiply by 5 to get back to the original value 8 x 5 = 40
Answer:
square with sides of 6 in
Step-by-step explanation:
Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.
Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.
Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in
200 plus 140 is 300
1400 plus 140 is 1540
200 plus 280 is 480
and 2800 plus 280 3080
