Applying properties to write equivalent expressions for 2x+5y+5(2x+5y)

levacccp [35]

Solving expression $2x+5y+5(2x+5y)$ we get $12x+30y$

Step-by-step explanation:

We need to solve the expression:

$2x+5y+5(2x+5y)$

Solving:

Multiplying 5 with terms inside the bracket:

$2x+5y+5(2x+5y)\\=2x+5y+10x+25y\\Combining\,\,like\,\,terms:\\=2x+10x+5y+25y\\=12x+30y$

So, Solving expression $2x+5y+5(2x+5y)$ we get $12x+30y$
