If 17+6p=9, then p=−4m. So, m is
Expand: (1)(a+2)(a−1)(2) (m−4)(m+6)(3) (p+8)(p−3)(4) (13+x)(13−x)(5) (3x+4y)(3x+5y)(6) (9x−5t)(9x+3t)(7) (m+23)(m−73)(8) (x+1x)(x−1x)(9) (1y+4)(1y−9)
Multiply:
(1) 3x by 4y
(2) 2y by 4y
(3) 8a by 4m
(4) −4x by 8x
(5) −5a by −8b
(6) −6p by 4pq
(7) 2a2 by 5a2
(8) 3x2b2 by 5x
(9) −7m2n2 by 4m
(10) −5a2b by −7ab2
