Se the FOIL method to evaluate the expression: (5+2)(4-5)

Mathematics

DaniilM [7]2 years ago

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

Given: AABC, m_ACB=90°,<br> CD 1 AB, m ZACD=60º,<br> BC = 6 cm<br> Find: CD, Area of AABC
just olya [345]

Answer:

Look below

Step-by-step explanation:

Given that CDB is 90 degrees, ACB is 90 degrees, and ACD is 60 degrees, we can determine that DCB = 90-60 = 30 degrees.

This means triangle BCD is a 30-60-90 (angle measures) right triangle

The proportions of the sides (from smallest to largest) is

x:x√3:2x

We are given that BC = 6 cm. This means...

2x=6

x=3

This means DB is 3 cm and CD is 3√3 cm

Using the linear pair theorem, we can find that Angle CDA is 90 degrees. This means ACD is also a 30-60-90 triangle.

x=3√3

x√3=9

2x=6√3

Now we need to find AB

AB = AD + DB

AB = 9 + 3

AB = 12 cm

Area = \frac{1}{2} bh = \frac{1}{2}(12)(3\sqrt3)=6(3\sqrt3)=18\sqrt3

AveGali [126]

Answer:

    The career planning process is ongoing and sequential. Since it is fluid rather than chronological, you move to the next step only when you are ready to do so, and you may move back and forth between steps at any given time. The career planning process is also cyclic. When career change is desired anytime during your work life, you may repeat the process once again. Data from the U.S. Bureau of Labor Statistics indicates that the majority of members of the labor force will make three to four major changes in their career during their 35 to 45 years of working. Because human beings are complex, each of us has unique aspirations, goals, potential for development, and limitations. Although we can follow the same process, career planning outcomes must be individualized.

Please help! Will mark brainliest! Not hard at all!
Trava [24]

Answer:

I think that the answer is A) $0.50

Step-by-step explanation:

So, if you want to figure out how much the strawberries cost for year 0, all you have to do is go to the point (0,4). For the first year the price of the strawberries have increased to 4.50. I know this because when you look at the graph, it looks like the point is in the middle of 4, which makes 4.50. So the price of the strawberries in year 1 is (1, 4.50). The price for year two is (2, 5) and so forth. This is what the pattern would be (0,4) (1, 4.50) (2, 5) (3, 5.50) (4,6) (5, 6.50) (6, 7) (7, 7.50) (8,8) (9, 8.50) (10, 9).......etc.
