Answer: Associative Property
This equation would be the associative property because you would have the ability to add or multiply these numbers, regardless of how they were grouped together
So a perfect square trinomial like
![\bf \begin{array}{cccccllllll} {{ a}}^2& + &2{{ a}}{{ b}}&+&{{ b}}^2\\ \downarrow && &&\downarrow \\ {{ a}}&& &&{{ b}}\\ &\to &({{ a}} + {{ b}})^2&\leftarrow \end{array}\qquad % perfect square trinomial, negative middle term \begin{array}{cccccllllll} {{ a}}^2& - &2{{ a}}{{ b}}&+&{{ b}}^2\\ \downarrow && &&\downarrow \\ {{ a}}&& &&{{ b}}\\ &\to &({{ a}} - {{ b}})^2&\leftarrow \end{array}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7Bcccccllllll%7D%0A%7B%7B%20a%7D%7D%5E2%26%20%2B%20%262%7B%7B%20a%7D%7D%7B%7B%20b%7D%7D%26%2B%26%7B%7B%20b%7D%7D%5E2%5C%5C%0A%5Cdownarrow%20%26%26%20%26%26%5Cdownarrow%20%5C%5C%0A%7B%7B%20a%7D%7D%26%26%20%26%26%7B%7B%20b%7D%7D%5C%5C%0A%26%5Cto%20%26%28%7B%7B%20a%7D%7D%20%2B%20%7B%7B%20b%7D%7D%29%5E2%26%5Cleftarrow%20%0A%5Cend%7Barray%7D%5Cqquad%20%0A%25%20%20%20perfect%20square%20trinomial%2C%20negative%20middle%20term%0A%5Cbegin%7Barray%7D%7Bcccccllllll%7D%0A%7B%7B%20a%7D%7D%5E2%26%20-%20%262%7B%7B%20a%7D%7D%7B%7B%20b%7D%7D%26%2B%26%7B%7B%20b%7D%7D%5E2%5C%5C%0A%5Cdownarrow%20%26%26%20%26%26%5Cdownarrow%20%5C%5C%0A%7B%7B%20a%7D%7D%26%26%20%26%26%7B%7B%20b%7D%7D%5C%5C%0A%26%5Cto%20%26%28%7B%7B%20a%7D%7D%20-%20%7B%7B%20b%7D%7D%29%5E2%26%5Cleftarrow%20%0A%5Cend%7Barray%7D)
has its middle term, by multiplying 2 * the left guy * the right guy
so.. .let's see your equation now x² - 3x +n
so.. the middle term is 3x, neverminding the sign
Answer:
The area of this triangle is 1888.32cm squared
Step-by-step explanation:
The area of a triangle is equal to its base times altitude divided by two. So the are of the following triangle is...
![A_{triangle} = \frac{bh}{2} = \frac{(67.2)(56.2)}{2} = \frac{3776.64}{2} = 1888.32cm^{2}](https://tex.z-dn.net/?f=A_%7Btriangle%7D%20%3D%20%5Cfrac%7Bbh%7D%7B2%7D%20%3D%20%5Cfrac%7B%2867.2%29%2856.2%29%7D%7B2%7D%20%3D%20%5Cfrac%7B3776.64%7D%7B2%7D%20%3D%201888.32cm%5E%7B2%7D)
