Given A(-4,8), D(-7,4), and H(-3,1), plot the points, and
trace the triangle.

See attached

Step-by-step explanation:

The points are plotted and connected to make a triangle

answer4 to the second power is 16

and 4 to the third power is 64,

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
