Simplify (n+7)*5n

$(n + 7) \cdot 5 n$

Step 1

Apply the distributive property.

$n (5 n) + 7 (5 n)$

Step 2

Simplify the expression.

Rewrite using the commutative property of multiplication.

$5 n \cdot n + 7 (5 n)$

Multiply $5$ by $7$ .

$5 n \cdot n + 35 n$

Step 3

Multiply $n$ by $n$ by adding the exponents.

Move $n$ .

$5 (n \cdot n) + 35 n$

Multiply $n$ by $n$ .

$5 n^{2} + 35 n$
