Question

please answer integers class 7 th ​

Answer 1

Answer:

28

Step-by-step explanation:

a × ( b + c ) = a × b + a × c

Given; a = - 7 , b = - 15 , c = 11

- 7 ( - 15 + 11 )

- 7 × - 15 + - 7 × 11

105 + ( - 77 )

105 - 77

28

Hope it helps!!

Answer 2

Answer:

acc to ques

a× (b×c) = a×b + a×c

substituting values

-7 ×(-15×11) = -7×-15 +-7 ×11

-7 × -165 = 105 -77

1155 =28

so your question is wrong as in a× (b×c)

there must be a × instead of + in (b×c)

and if you solve this

then

-7 ×(-15+11) = -7×-15 +-7 ×11

-7 ×(-4) = 105 - 77

28 =28

LHS = RHS

hence proved
