Question

 a + ( 45 + 35 )   90  + a 

Answer 1

А+(45+35)*90+а=2а+7200

Answer 2

It seems like you've written a mathematical expression with some spaces. Let's simplify it:

a + (45 + 35) + 90 + a

First, we can simplify the expression inside the parentheses:

a + (80) + 90 + a

Now, we can combine like terms:

a + a + 80 + 90

Next, add the 'a' terms together:

2a + 80 + 90

Now, add the constants:

2a + 170

So, the simplified expression is:

2a + 170
