A. a + ( - a)

Because it’s the same thing as: a - a

And if you plug in any value for example:
2 - 2 that would be 0

(3x-8)(2xsquared4x-9) multiply and write the result in descending order

RSB [31]

Hello there, you can proceed with the multiplication of these factors using the FOIL method (which stands for first, outer, inner and last) multiply I assume that by descending order, you mean by decreasing power. If it were so, the answer is 6(x^3)12(x^2)-16(x^2)32x-27x+72.

What is the answer of a ?

Scorpion4ik [409]

Answer:

<h2>2.2</h2>

Step-by-step explanation:

Use the cosine law (look at the picture).

We have:

$a=a\\b=4\\c=3\\\gamma=32^o$

$a^2=4^2+3^2-2(4)(3)\cos32^o$

$\cos32^o\approx0.848$ → look at the second picture

$a^2=16+9-24(0.848)\\\\a^2=25-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2$

Answer:

<h2><em><u>5.71</u></em><em><u>%</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

Cost price of the car when Arjun bought = ₹ 3,50,000

Cost price of that same car after 1 year = ₹ 3,70,000

<em><u>So</u></em><em><u>,</u></em>

Amount of money increased on the car's price

= ₹ (3,70,000 - 3,50,000)

= ₹ 20,000

<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>

Percentage of increase on the car's price

$= \frac{20000}{350000} \times 100$

<em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

$= \frac{2}{35} \times 100$

<em>[</em><em>On</em><em> </em><em>further</em><em> </em><em>Simplification</em><em>]</em>

= 5.7142......

= 5.71 (approx.)

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Percentage</u></em><em><u> </u></em><em><u>in</u></em><em><u> </u></em><em><u>increase</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>car's</u></em><em><u> </u></em><em><u>price</u></em><em><u> </u></em><em><u>was</u></em><em><u> </u></em><em><u>5.71</u></em><em><u>%</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
