Area= a*height
the formula for an isosceles trapezoid is 1/2(base1+base2)*height. 1/2 base 2 and 2a will simplify to a base length of a. a times height or a*height
You add $5.38 & $15.95, which equals $21.33. Then subtract $21.33 from $38.12. Your answer is $16.79. That's how much Shane spent on the book.
Answer:
Equation of the line: 
.
Step-by-step explanation:
Let 
and 
denote the coordinates of these two points, respectively.
Calculate the slope 
of this line:
.
Notice that the slope is zero because the two points have the same 
-coordinates (
) even though their 
-coordinates are distinct (
.)
Equation for this line in point-slope form:
.
.
Rewrite and simplify to obtain the equation of this line in slope-intercept form:
.
The -term was eliminated because the slope was zero.
