The main formula is (a+b)^3=a^3+3(a^2)b+3a(b^2)+b^3
let be a=4x, b=3y
so (4x + 3y)^3=(4x)^3+3.(4x)^2.(3y)+3.4x.(3y)^2+(3y)^3
= 64x^3+144x^2.y+108x.y^2+27y^3
The coefficient of the second term in the expansion of the binomial (4x + 3y)3 is 144

14 Metric System Conversion. Convert 26.2 miles into kilometers and round to the nearest tenth. (Hint: 1 mile= 1.609 km)

Mekhanik [1.2K]

Answer:

42.1558 km

Step-by-step explanation:

We know that 1 mile = 1,609 km

Then use this data as a conversion factor.

If we want to transform miles to kilometers then our conversion factor should be:

$\frac{1,609\ km}{1\ miles}$

Now we must multiply the number of miles by this factori and thus we obtain the equivalent in kilometers

$26.2*\frac{1,609\ km}{1\ miles} = 42.1558 km$

Answer:

The value of $4x+12-x^2$ is 16.

Step-by-step explanation:

The given expression is $4x+12-x^2\ at\ x=2$ .

Put x = 2 in the above expression as follows :

$4x+12-x^2=4(2)+12-(2)^2\\\\=8+12-4\\\\=16$

Hence, the final answer is 16.
