Answer:

x = 0

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

6x + 7y = 4x + 4y

y = -4

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute:                               6x + 7(-4) = 4x + 4(-7)
  2. Multiply:                                   6x - 28 = 4x - 28
  3. Add 28 on both sides:            6x = 4x
  4. Subtract 4x on both sides:     2x = 0
  5. Divide both sides by 2:           x = 0

Answer:

6 square units

In oder to do this, you need graph paper to make it easier and then mark your graph paper with the quadrants.

I got 3 unites for the height and 4 units for the base

4 x 3 = 12 square units

however the formula for a triangle is Ab/2

so divide 12/2 = 6

So its 6 square units
