Answer:
-14 = -14
Step-by-step explanation:
This question can be solved showing distributive property of multiplication over addition
a*(b +c)=(a*b)+(a*c)
-2(9+(-2))=(-2*9)+(-2*-2)
-2*7=-18+4
-14=-14

Answer:
8/35
Step-by-step explanation:
a×(b+c) = 1/4 × (2/5 + 2/7)
= 8/35
a×b + b×c = (1/4 × 2/5) + (1/4 × 2/7)
= 1/10 + 1/14
=24/140
=8/35
