Question

Verify the following and name the property used.
−3 5 7 −3 5 −3 7
4 x[6+3]=(4 x6)+(4 x3)

Answer 1

Answer:

first always we should do the bracket

6+3=9

4×9=[4×6]+[4×3]

we are going one by one

4×6=24

4×9=24+[4×3]

4×3=12

4×9=24+12

24+12=36

(36)

we will keep it away and solve the next

-357-45-37

=225

then we should add both

225+36

=261

the answer is 261
