Question

7(4n-9) - 3(n-7)
Use the Distributive Property to
write an equivalent expression.​

Answer 1

Answer:

• 25n - 42

Step-by-step explanation:

Distributive Property:

• a(b + c) = ab + ac

Given:

• 7(4n-9) - 3(n-7)

Simplify:

• 7(4n-9) - 3(n-7) =
• 28n - 63 - 3n + 21 =
• 25n - 42

Answer 2

Answer:

$25n - 42$

Step-by-step explanation:

$7\left(4n-9\right)-3\left(n-7\right)$

$7\left(4n-9\right)$

$28n-63$

$=28n-63-3\left(n-7\right)$

$-3\left(n-7\right)$

$3n+21$

$=28n-63-3n+21$

$\mathrm{Group\:like\:terms}:-$

$28n-3n-63+21$

$=25n-42$
