Hello. I need help on this question. Please answer if you know. Provide the answer with working. Thanks.
11Alexandr11 [23.1K]

Answer:

a) - 11x - 94y / 12    b)  x -4 / 5- 3x   c) 12x - 11 /10y

Step-by-step explanation:

a)  2x - 6y / 4    -  4y - x/ 12    -   4x - 20y /3

6x - 18y / 12 -     4y - x / 12              -  16x - 80y / 12

= 5x - 14y / 12     - 16x - 80y / 12

- 11x - 94y / 12

b) x /5 -    4/ 3x =  x -4 / 5- 3x

c) 2x -3/ 5y  -    5- 2x / 10y + x/y

4x - 6 /10y   -  5-2x/ 10y +  10x / 10y

2x - 11 / 10  + 10x / 10y

= 12x - 11 /10y

Use your shapes to create a new shape with an area of 1 square unit that is not a square. Trace your shape.
Elena-2011 [213]

A new shape with an area of 1 square unit that is not a square can be formed by combining two small triangles

<h3>How to determine the new shape?</h3>

The given parameters are:

  • Area of square = 1 square unit
  • Large triangles = 2
  • Medium triangles = 1
  • Small triangles = 4

The area of each small triangle is:

Area = 0.5 square unit

Multiply both sides by 2

2 * Area of triangle = 1 square unit

Substitute Area of square = 1 square unit

2 * Area of triangle = Area of square

This means that a new shape can be formed by combining two small triangles
