Answer:
a)2x-3y
b)4(9a-4)
Step-by-step explanation:
<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:
<h2>
Answer:</h2>
<u>, "six and one over two ft".</u>
<h2>
Step-by-step explanation:</h2>
Let's considerate the fact that the garden has a <u>square shape</u>.
<h3>1. Finding values of interest.</h3>
Amount of fence that the gardener already has: ft.
Length of one side: ft.
If one side measures ft, and the square garden has 4 sides of equal length, because it's a square, then we must multiply the measure of one side by 4 to find the total length of fence needed:
<h3>
2. How much more does he need?</h3>
The gardener already has , which equals . Hence, the difference between the amount needed and the amount that the gardeneralready has will give us the remaining amount required. Let's do that:
<h3>3. Express your result.</h3>
