Answer: The correct answer would be -85.
Step-by-step explanation: This is because the -5 becomes positive because it is inside parentheses.
This would make the expression: -425 ÷ 5.
-425 ÷ 5 is equal to -85.
Hope this helps and have a nice day! :)
we know that
the volume of a rectangular prism is equal to

where
L is the length of the box
W is the width of the box
H is is the height of the box
in this problem we have




<u>Find the length of the box</u>
Using a graph tool-------> we will determine the roots of the equation of volume
see the attached figure
the roots are

so

therefore
<u>the answer is</u>
the length of the box is equal to 
Answer:



Step-by-step explanation:
From inspection of the given diagram:
<h3><u>Part (a)</u></h3>
A right angle is 90° and is represented by the ∟ symbol.
To find x, <u>equal</u> the sum of the angles to 90° and solve for x:








<h3><u>Part (b)</u></h3>
To find the degree measure of each angle, substitute the found value of x into the expression for each angle.


Answer:
The sides are as follows: 
Step-by-step explanation:
Starting with the side y, we can use the tan to solve for y:

The side x can be determined using sin:

So, the sides as as follows: 
(you can also verify this result is correct using the Pythagorean theorem)
