To be able to solve clearly this problem, the best thing
to do is to plot the graph (see attached pic). From the graph we can see that
the points form a trapezoid.
The base is formed by the segment connecting point A and
point B.
While the two heights: shorter one by the segment
connecting points A and D, and the longer one by the segment connecting points
B and C.
The formula for area of trapezoid is given as:
A = b (h1 + h2) / 2
Where,
<span>b = base of the trapezoid
= 3 – (-4) = 7</span>
h1 = shorter height = 2 – (-2) = 4
h2 = longer height = 2 – (-5) = 7
Therefore the area is:
A = 7 (4 + 7) / 2
A = 77 / 2
<span>A = 38.5 </span>
Answer:
Part 5) Option b
Part 6) Option d.
Step-by-step explanation:
Part 5) we know that
The area of a square is equal to
where
b is the length side of the square
we have
substitute
Solve for b
take square root both sides
Remember that
substitute
Applying property of exponents
Part 6) we know that
The volume of a cube is equal to
where
b is the length side of the cube
we have
substitute
Solve for b
take cubic root both sides
Remember that
substitute
Applying property of exponents
Answer:
Step-by-step explanation:
- Add 5/4 to each side, so it now looks like this: x = -11/20
