The answer is 73.5

To make it a lot easier split the shapes into a rectangle and triangle.
The rectangle is a tad easier because the measurements are given here.

5 x 12 = 60 (rectangle area)

To find the triangle find the base then height. The base is 3cm and the height is 9cm (shown above)

9 x 3 = 27
Divide that by 2 because it's a triangle and you get 13.5.

Add those two numbers and voila you have your answer of 73.5.

Find an equation of the plane that passes through the point P0 = (6, 3, 2) and is parallel to the xy-plane. g
Nutka1998 [239]

The <em>xy</em>-plane has a normal vector of 〈0, 0, 1〉, and any plane parallel to it will have the same normal vector.

Then the equation of the plane through (6, 3, 2) that is parallel to the <em>xy</em>-plane has equation

〈<em>x</em> - 6, <em>y</em> - 3, <em>z</em> - 2〉 • 〈0, 0, 1〉 = 0

==>   <em>z</em> - 2 = 0

==>   <em>z</em> = 2

Explain how to isolate the variable in the equation -2/3n + 7 = 15
vodka [1.7K]

Answer:

n = -12

Step-by-step explanation:

(-2/3)n + 7 = 15          

(-2/3)n+7-7 = 15-7               Subtract by 7 on both sides

(-2/3)n = 8                         Multiply by the reciprocal of the fraction, which is                                                                                                  

(-2/3)n*(-3/2) = 8(-3/2)      This makes it so you get n *1 and isolates n.

n = -24/2 = -12
