Answer:

2) Subtraction Property of Equality Properties

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Addition Property of Equality - Adding on both sides
  • Subtraction Property of Equality - Subtracting on both sides
  • Multiplication Property of Equality - Multiplying on both sides
  • Division Property of Equality - Dividing on both sides
  • Transitive Property - If a = b and b = c, then a = c
  • Symmetric Property - If a = b then b = a

Step-by-step explanation:

<u>Step 1: Define</u>

4m + 1 = 7 → 4m = 6

<u>Step 2: Identify</u>

We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.

An equilateral triangle with side length 7 cm is shown in the diagram, work out the area of the triangle.
ElenaW [278]
If a triangle has sides of 7 cm and it is an equilateral you can draw a line right down the middle to form two congruent triangles.

These smaller triangles have a hypotenuse of 7cm and a base of 3.5 cm (7/2)

To work out the height, use Pythagoras’ theorem.

a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides

7^2 - 3.5^2 = 36.75

Square root answer

= 6.06 cm

That’s the height of the triangle

Area of a triangle is base x height divided by 2

So 7 x 6.06 = 42.43…

/2

= 21.2 cm^2 to one d.p
