Cos=adjacent/hypotenuse
Cos30=x/20
x=cos30 *20
Sorry I don’t have a calculator right now
-4(3-x)+6=2(x-3)
-12+4x+6=2x-6
-6+4x=2x-6
-6+6=2x-4x
0=-2x
0/x=-2
Assuming you want them multiplied
f(x)*g(x)=(3x+5)(x^2)=3x³+6x²
Answer:
even if the first answer is wrong? Just kidding, the first one is -9, second is 0, third is 9, and last is 18
Step-by-step explanation:
