Answer:
Step-by-step explanation:
The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.
Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:
Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.
No, 12/15 is less than 12/14
The correct question is
<span>
ABCD is a rectangle. what is the length of the diagonals if AC= 3y/5 and BD= 3(y-4)see the figure attached to better understand the problem
we know that
</span><span>Given AC and BD are diagonals. In a rectangle diagonals are equal.
</span>
Therefore AC = BD
=> 3y/5 = 3y - 4
=> 3y = 5(3y - 4)
=> 3y = 15y - 20
=> 12y = 20
=> y = 20/12 = 5/3
Therefore AC = 3y/5
= 3(5/3)/5
= 1 units
and BD = 3y - 4
= 3(5/3) - 4
= 5 - 4
= 1 units
the answer is
The length of each diagonal is 1 units
Answer:
(5,3)
Step-by-step explanation:
x=17-4y
x=17-4x+8
x=25-4x
5x=25
x=5
y=x-2
y=5-2
y=3
(5,3)
Answer:
y = 4

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
-15 + 10y = 25
<u>Step 2: Solve for </u><em><u>y</u></em>
- [Addition Property of Equality] Add 15 on both sides: 10y = 40
- [Division Property of Equality] Divide 10 on both sides: y = 4
