Answer:
7.595
Step-by-step explanation:
Use PEMDAS
So if we know we need to use the parenthesis first since P stands for parenthesis
So solve (0.25 x 4.1) first.
(0.25 x 4.1) =1.025
We know that (0.25 x 4.1) =1.025 so we plug in 8.62-1.025
When subtracted we get the answer of 7.595
That's a quadratic equation in

, which means we get an extra square root and

at the end.

We factor,

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)
