Question

2. Using distributive law, simplify:
a) (-13) x (-22) + (-13) × (-11)
b) 773 x (-97) + (-773) x 3​

Answer 1

Answer:

a) (-13) x (-22) + (-13) x (-11) = (-13) x [(-22)+(-11)] = (-13) x (-33) = 429

b) 773 x (-97) + (-773) x 3 = (-773) x (97+3) = (-773) x 100 = -77300

Answer 2

Hi mate!,
a) (-13)*(-22)+(-13)*(-11)
(- 13)(-22+-11)
(-13*-22)+(-13*-11)
286+143

§§ANS=429

b)773*(-97)+(-773)*3
773*(-100+3)+( -773*3)
-77300+2319+(-2319)
-74981-2319
-77300

OR

773* (-97-3)
773* (-100)
-77300

§§ANS. -77300
