Which of the following equations have no solutions? Check all that are true. 13x − 4 = 13(x − 3) -2x + 14 = 14x + 6 7x − 8 = 3x + 7 + 7x 6x − 3 = 2x − 10 + 4x -6(2x + 3) = -2(6x + 11

Translate the word phrase into a math expression. 15 fewer than the product of 4 and a number. (pls immediately)

Can someone answer this question for me

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
