Use the binomial theorem to write the binomalexpadion (a +2b)^4

Mathematics

Nataly_w [17]3 years ago
5 0
The binomial theorem for a binomial in the format (x + y) to the fourth power is 

x⁴ + 4x³y + 6x²y² + 4xy³ + y⁴

So now we plug in for the x- and y-values

a⁴ + 4a³(2b) + 6a²(2b)² + 4a(2b)³ + (2b)⁴

Simplify this to become:

a⁴ + 8a³b + 6a²(4b²) + 4a(8b³) + 16b⁴

Now simplify to:

a⁴ + 8a³b + 24a²b² + 32ab³ + 16b⁴

Eduardwww [97]

Answer:

14000

Explaination:

spwithvat = sp without vat + 13% of sp without vat

let, sp without vat be x.

sp with vat= x + 13% of x.

or, 13447 = x + 13/100 × x

or, 1344700 = 113x

or, x= 1344700/113

x = 11900

Let, mp be y.

sp with vat = mp - 15% of mp

or, 11900 = y - 15/100 × y

or, 1190000 = 85y

or, y= 1190000/85

y= 14000

I need to solve for x
podryga [215]

Answer:

30 degrees

Step-by-step explanation:

This is an isosceles triangle having 2 equal sides and 2 equal base angles.

since the measurement of all the internal angles of the triangle is 180 degrees and we know that each base angle is 75 degrees

solving for x:

75 + 75 + x = 180 degrees

150 + x = 180

x = 180 - 150

x = 30 degrees
