Answer:

Given:

Step-by-step explanation:
Property used: <em>An exterior angle of a triangle is equal to the sum of the opposite int</em><em>e</em><em>rior angles.</em>
<em>
</em>
Answer:

• Apply additional property of equality:

• Apply cross multiplication, multiply either sides by -3:

We can split this up into 1 trapezium and 2 triangles
Area = (3/2) * (6 + 7) + 1/2 * 3 * 6 + 1/2 * 3 * 4
= 19.5 + 9 + 6
= 34.5 answer
Its B
-1x(6x - 8)
= -x(6x - 8)
= -x(6x) - x(-8)
= -6x^2 + 8x
All you need to do is change the point st which the line crosses the y-axis. 1/2x + will work.
