Answer:
X=20. Our x coordinate is 20.
Step-by-step explanation:
Based from the given slope of 1/2 and a y-intercept of -6, our equation of a line is y=x/2 -6. To remove the fraction we can multiply the equation by 2 to get 2y=x-12. Using this substitute the value of y coordinate 4.
2(4)= x-12
8+12 =x 
X=20.

Answer:
   115 square units
Step-by-step explanation:
The area of a parallelogram is the product of base length and height. The height is the perpendicular distance between the bases.
   A = bh
   A = (23)(5) = 115 . . . . square units

Answer:
105 feet.
Step-by-step explanation:
The longer diagonal is opposite the longer angle in the parallelogram.
The longer angle = 180 - 36 = 144 degrees. (Reason: he same side angles  are supplementary).
So, by the law of cosines:
x^ 2 = 40^2 + 70^2 - 2*40*70 cos 140    where x = the diagonal.
x^2 =  11030.50
x = 105.03 feet.
