Answer:
6^-8 or 1/ 6^8
Step-by-step explanation:
When there is a fraction with the same base, then subtract the exponent of the denominator from the exponent of the numerator.
6^-3 / 6^5 = 6^(-3-5) = 6^-8
Answer:
(c) 714.96 = 21.6(w +4.7)
Step-by-step explanation:
The area of the rectangular park will be the product of its length and width. This relation is used to write an equation to find the original width of the park.
<h3>Width</h3>
Let w represent the original width of the park in meters. The new width is 4.7 meters more, so is represented by (w +4.7).
<h3>Other dimensions</h3>
The length of the park is given as 21.6 meters. The area is given as 714.96 square meters.
<h3>Area formula</h3>
The various dimensions of the park are related by the area formula:
A = LW
714.96 = 21.6(w +4.7)
For this case we have the following quadratic equation:
Where:
Its roots will be given by:
The roots are:
