<h3>a)</h3>
we want to expand the following expression:

well to do so we consider distributive property thus distribute:

reduce fraction which yields:

simplify Parentheses:

<h3>b)</h3>
in the expression there's a common factor of 4 therefore factor it out:

$9.75 because one taco is 0.75 and 13 x 0.75 is $9.75
You would use PEMDAS
But since any number divided by 1 is the number by which it is divided by then you can eliminate that. Now your problem looks like this:
8✖️4➕9✖️56➕57
Since there are no parentheses or exponents then you would multiply.
8✖️4= 32
32➕9✖️56➕57
Then multiply the other multiplication problem.
9✖️56= 504
32➕504➕57
Now you can add all of the numbers together
32➕504=536
536➕57=593
Your answer is 593
Hope this helps! :3
