- Identify the rule of algebra illustrated by the statement. a. x+9=9+x b. 5x32=5x32 c. 2+5x2y2=2y2+5x2y2arrow_forwardLet A = · [ -3] and B = -2 (a) Find AB, A-1, and B-¹. AB = | A-1 = 2-2 B-1 (b) Show that (AB)-1 = B-¹A-1, (AB)-1 B-1A-1 5-3 2-1 =arrow_forwardLet a = (-5, 5, 4) and b = (-1,-4, 5). (a) à x b (41,-21,24) x (b) b × à = X (c) (ã × b) × b) x ã = (d) ( ã × b ) . b = |arrow_forward
- Explain it correctly 1(b) onlysarrow_forwardWhen does a(b+c) result as a positive value for ac?arrow_forwardLet X and y be two real numbers different from zero. Simplifying the expression 2xy ( - x2y) + (2x2y)3 : (8x3y), we get: 1 2..3 (a) 2 - 2 1 (b) 3y 0 (c) 2xy 3 (d) - zx3y2 (e) zx2y 3 3arrow_forward
