Answer:
$626.75
Step-by-step explanation:
<u>First, we must find how much tax will be added to the TV's price:</u>
<u>Step 1: Convert the percentage to a decimal:</u>
To convert a percentage to a decimal, divide it by 100
8.25/100 = 0.0825
<u>Step 2: Multiply the TV's price by that decimal:</u>
578.98 * 0.0825 = 47.76585
So $47.76585 will be added to the price
<u>Now, we can calculate the total price:</u>
<u>Step 3: Add the tax we jsut calculated to the TV's price to find total price:</u>
578.98 + 47.76585
= 626.74585
<u>Step 4: Round to the nearest cent (2 decimal places)</u>
626.75
So the total price is $626.75
Answer:
C
Step-by-step explanation:
49x² + 28xy + 4y² ← is a perfect square of the form
(ax + by)² = a²x² + 2abxy + b²y²
49 = 7² ⇒ a = 7 and 4 = 2² ⇒ b = 2
2ab = 2 × 7 × 2 = 28
Hence
49x² + 28xy + 4y² = (7x + 2y)²
with factor 7x + 2y ⇒ C
X = 3
2(4x - 3) - 8 = 4 + 2x
1. Distribute
8x - 6 - 8 = 4 + 2x
2. Collect like terms
8x - 14 = 4 + 2x
3. Collect like terms again (add 14 and subtract 2x)
6x = 18
4. Divide by 6
x = 3
