Answer:
6/12 or 1/2
Step-by-step explanation:
Multiply Across
Numerators 3 x 2 = 6
3 x 4 = 12
6/12
(or 1/2, simplified)
The missing proof is the third statement
¹²³⁴⁵⁶⁷⁸⁹⁰⁹⁸⁷⁶⁵⁴³²¹
₁¹₁¹₁
Add the coefficients of like terms.
a) (6x³ +8x² -2x +4) + (10x³ +x² +11x +9)
= (6+10)x³ + (8+1)x² + (-2+11)x + (4+9)
= 16x³ +9x² +9x +13
b) (16x³ +9x² +9x +13) + (3x -2)
= 16x³ +9x² + (9+3)x + (13-2)
= 16x³ +9x² +12x +11
