A <u>trapezoid</u> is a quadrilateral with exactly one pair of parallel sides.
Formula for area: 
In this formula, the bases are the parallel sides.
Now plug the information into the formula.
.
Follow your order of operations, simplify inside the parentheses first.
.
(1/2)(8) is 4 so we have (4)(9) which is 36.
So the area of the trapezoid is 36.
Answer:
-25=x
Step-by-step explanation:
20=10x-6(2x+5)
20=10x-12x-30
20=-2x-30
+30 +30

Answer:
y = (x-0)^2 + (-5) ⇒ y = x^2 - 5
Step-by-step explanation:
The general vertex form of the parabola y = a(x - h)² + k
Where (h,k) is the coordinates of the vertex.
As shown at the graph the vertex of the parabola is the point (0, -5)
So,
y = a(x-0) + (-5)
y = ax^2 - 5
To find substitute with another point from the graph like (1,-4)
So, at x = 1 ⇒ y = -4
-4 = a * 1^2 - 5
a = -4 + 5 = 1
<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
