Se the FOIL method to evaluate the expression: (5+2)(4-5)
DaniilM [7]

The FOIL <em>method</em> is a method of <u>expanding</u> two given <u>brackets</u> by following the required <u>steps</u>. Thus using the FOIL <em>method</em>, the required answer is: -7

<em>Expansion</em> of <u>brackets</u> may be done using different <em>methods</em>, but these <em>methods</em> would give the same answer. Some <em>methods</em> that can be used are the <u>binomial</u> expansion method, FOIL method, etc.

The FOIL <u>method</u> is a <em>shortened</em> form of the<u> steps</u> required for the process. These required <u>steps</u> are <u>First</u>, <em>Outside</em>, <em>Inside</em>, and <u>last.</u>

Thus to <u>expand</u> the given <em>brackets</em> in the question, we have;

(5+2)(4-5) = 5(4 - 5) + 2(4 - 5)

                = 20 - 25 + 8 - 10

                = 28 - 35

(5+2)(4-5) = -7

Thus using the FOIL <u>method</u>, the <u>answer</u> to the question is -7.

<em>Quick check</em>: (5+2)(4-5) = (7)(-1)

                             = -7

explain how you can use a straightedge and a protractor to show that each angle you formed by a bisector is one-half the origina
Natasha2012 [34]
You can do that by simply measuring the main angle and then measuring each of the two angles. If you bisected the angle correctly, you will find that each of the two angles is equal to half the original.

You can measure the angle by following these steps:
1- Place the straightedge on the base of the angle.
2- Slide the protractor over it until the vertex of the angle is at the zero of the protractor.
3- Measure the angle.
