Answer:
<em>2a² = c²</em>
Step-by-step explanation:
Right triangles follow the Pythagorean Theorem, <em>a² + b² = c².</em> The hypotenuse <em>(c)</em> must be the longest of the sides. In the given triangle, both legs measure <em>a</em> units. So, <em>a = b.</em> Therefore, we have <em>a² + a² = c²</em> or <em>2a² = c²</em><em>.</em>
Expression that represents the change from $20 after the purchase of an item that costs d dollars is:

Answer:
$4748.80
Step-by-step explanation:
First, find the cost with 20% off, by multiplying the price by 0.8
5600(0.8)
= 4480
Find the cost with tax, by multiplying this by 1.06
4480(1.06)
= 4748.8
So, the sale price, including tax, is $4748.80
