Question

The expression was rewritten using the ( blank?) i’m so confused pls help

Answer 1

I am solving the equation in simplest way

Line:-1

$\\ \tt\bull\longmapsto 9.(7+1)$

• Solve the bracket

$\\ \tt\bull\longmapsto 9(8)$

$\\ \tt\bull\longmapsto 72$

Line:-2

$\\ \tt\bull\longmapsto 9.7+9.1$

$\\ \tt\bull\longmapsto 63+9$

$\\ \tt\bull\longmapsto 72$

Answer 2

Answer:

It was solved using distributive property

Step-by-step explanation:

${ \tt{9•(7 + 1)}}$

• 9 outside the bracket is distributed to each value in the bracket:

$= { \tt{(9•7 + 9•1)}} \\ \\ = { \tt{63 + 9}} \\ \\ { \tt{ = 72}}$
