Question

(2m+2)(5n+9)+(-5m+5)(n+9)

Answer 1

(2m+2)(5n+9)+(-5m+5)(n+9)= 4m×14n+10m×9n=40m+126n

Answer 2

Sure, I can help with that! It looks like you've provided an algebraic expression, and you'd like to simplify it. Let's start by expanding the given expression step by step.

First, we'll use the distributive property to expand the expression: (2m + 2)(5n + 9) + (-5m + 5)(n + 9)

Expanding the first part: = 2m * 5n + 2m * 9 + 2 * 5n + 2 * 9

Expanding the second part: = -5m * n - 5m * 9 + 5 * n + 5 * 9

Now, let's simplify each part: = 10mn + 18m + 10n + 18 - 5mn - 45m + 5n + 45

Combining like terms: = (10mn - 5mn) + (18m - 45m) + (10n + 5n) + (18 + 45) = 5mn - 27m + 15n + 63

So, the simplified form of the given expression is: 5mn - 27m + 15n + 63
