Create a word problem that can be represented by the expression below. then, represent each product or quotient as a single rational number. 8 times (-0.25), and -6 divide by (1 1/2) plz i will give you 100 points

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
