I think that it might be B. Im not 100% sure though.
<em>x = 20/7</em>
<em>x = 2 6/7</em>
- Step-by-step explanation:
<em>Hi there !</em>
6x - 9 - 2(1 - x) = x + 9
<em>6x - 9 - 2 + 2x = x + 9</em>
<em>6x + 2x - x = 9 + 9 + 2</em>
<em>8x - x = 20</em>
<em>7x = 20</em>
<em>x = 20/7</em>
<em>x = 2 6/7</em>

<em>Good luck !</em>
Answer:

Step-by-step explanation:
3 = −5⁄7[−4] + b
2 6⁄7

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE</em><em> </em><em>OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 1 2⁄5 [or 7⁄5] becomes −5⁄7.

Answer:

Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are


Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=
Area of trapezoid=
