<em>Answer:</em>
<em>4</em>
<em>Step-by-step explanation:</em>
<em>2(6x+4)-6+2x=3(4x+3)+1</em>
<em>=14x+2=12x+10</em>
<em>=14x+2-2=12x+10-2</em>
<em>=14x=12x+8</em>
<em>=14x-12x=12x+8-12x</em>
<em>=2x=8</em>
<em>=2x/2=8/2</em>
<u><em>x=4</em></u>

Answer:
8192
Step-by-step explanation:
The number of subsets of an n-element set is 2^n.
Your set has 13 elements, so has 2^13 = 8192 subsets.
__
This count includes the empty set and the full set.
Answer:
-1/2
Step-by-step explanation:
Rearranging this equation to slope-intercept form, we see the slope (x-coefficient) is 2:
2x = 7 + y . . . . . add y
y = 2x -7 . . . . . . subtract 7
The slope of the perpendicular line is the opposite of the reciprocal of this:
-1/2 = slope of perpendicular
Answer:
<h2>The height is 10 m</h2>
Step-by-step explanation:
Area of a trapezoid is given by
<h3>
</h3>
where
a and b are the bases
h is the height
From the question
A = 135 m²
a = 20m
b = 7 m
Substitute the values into the above formula and solve for the height
That's
<h3>
</h3>
<u>Divide both sides by 27</u>
That's
<h3>
</h3>
We have the final answer as
<h3>10 m</h3>
Hope this helps you
