Danny is making hot chocolate. The recipe calls for 1/2 cup of powder to 2 cups of warmed milk. If Danny wants to make 6 cups of hot chocolate, how much powder does he need? PLEASE HELP

Which sum or difference identity would you use to verify that cos (180° - q) = -cos q? a.) sin (a -b) = sin a cos b – cos a sin b b.) cos (a -b) = cos a cos b – sin a sin b c.) cos (a -b) = cos a cosb + sin a sin b d.) sin (a + b) = sin a cos b + cos a sin b

Solve the following: 12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1) 364x–64x=300x

What multiplys to be 1 but adds up to be 4
