First, find the area: Area (A) = length (L) x width (w) = 14 x 7 = 98 ft²
Next, find the cost:
98 ft² x $.75/ft² = $73.50
Example 1 Perform the indicated operation for each of the following.
<span>(a) </span>Add to
<span>(b) </span>Subtract
Solution
(a) Add to .
The first thing that we should do is actually write down the operation that we are being asked to do.
In this case the parenthesis are not required since we are adding the two polynomials. They are there simply to make clear the operation that we are performing. To add two polynomials all that we do is combine like terms. This means that for each term with the same exponent we will add or subtract the coefficient of that term.
In this case this is,
[Return to Problems]
(b) Subtract from .
Again, let’s write down the operation we are doing here. We will also need to be very careful with the order that we write things down in. Here is the operation
TAZZ WAZ HEA :)
In the given mathematical
value of 51, 487 to round off this number to the nearest thousand, we can
elaborate the number values using the expanded form to clearly see the order
position:
<span><span>1. </span><span> 50, 000 = ten
thousands</span></span>
<span><span>2. </span><span> 1, 000 =
thousands</span></span>
<span><span>3. </span><span> 400 = hundreds</span></span>
<span><span>4. </span><span> 80 = tens</span></span>
<span><span>5. </span><span> 7 = ones</span></span>
Now we can observe the
numerical value of 51, 487 than 1, 000 is the number in which belongs to the
thousands’ position hence since the nearest number is 400 the value will be 51,
000.
