Rebekah said that 10 to the power of 3 is 30 because 10+10+10=30. do you agree? explain.

Find the area of an equilateral triangle with a side of 6 inches

Find the value of x for which line a is parallel to line b

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
