15x + 28y = 116
x + y = 6

that would be ur system of equations

I've answered your other question as well.

Step-by-step explanation:

Since the identity is true whether the angle x is measured in degrees, radians, gradians (indeed, anything else you care to concoct), I’ll omit the ‘degrees’ sign.

Using the binomial theorem, (a+b)3=a3+3a2b+3ab2+b3

⇒a3+b3=(a+b)3−3a2b−3ab2=(a+b)3−3(a+b)ab

Substituting a=sin2(x) and b=cos2(x), we have:

sin6(x)+cos6(x)=(sin2(x)+cos2(x))3−3(sin2(x)+cos2(x))sin2(x)cos2(x)

Using the trigonometric identity cos2(x)+sin2(x)=1, your expression simplifies to:

sin6(x)+cos6(x)=1−3sin2(x)cos2(x)

From the double angle formula for the sine function, sin(2x)=2sin(x)cos(x)⇒sin(x)cos(x)=0.5sin(2x)

Meaning the expression can be rewritten as:

sin6(x)+cos6(x)=1−0.75sin2(2x)=1−34sin2(2x)

Answer:

{-6 , 7 , 1} {9 , -3 , -4} {5 , -8 , 4} --- 2, 2, 1

Step-by-step explanation:

Number 1: {-6 , 7 , 1} {9 , -3 , -4} {5 , -8 , 4} --- 2, 2, 1

Number 2: {-6 , -3 , 9} {4 , 7 , -8} {5 , 1 , -4} --- 0, 3, 2

Number 2: {-4 , 5 , 1} {7 , 4 , -8} {-6 , -3 , 9} --- 2, 3, 0
