If you're aware that the area inside a (symmetrical) parabola is 2/3 of the area of the enclosing rectangle, you can compute the desired area as follows.
The parabolic curve is 4-1 = 3 units wide between x=1 and x=4. It extends upward 2.25 units from y=4 to y=6.25, so the enclosing rectangle is 3×2.25 = 6.75 square units. 2/3 of that area is (2/3)(6.75) = 4.5 square units.
This region sits on top of a rectangle 3 units wide and 4 units high, so the total area under the parabolic curve is ...
area = 4.5 +3×4 = 16.5 . . . square units
Answer:
The original example of a situation in which the Distributive Property could be used. Calculation with distribution and calculation without distribution is below.
Step-by-step explanation:
Distributive property:
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
i.e A(B+C) = AB + AC
For example:
Using distributive property,
Now, without distributive property we have
