The condition for an expression to be an <u>identity </u>is that both sides of equality must give the same value.
In this case, the equation that fulfills that condition is the first equation (1).
<u>Let’s prove it:</u>
1)
Applying distributive property:
Joining together similar terms on both sides of the equality:
<h2>
>>>>>>>This is true and fulfills the condition of identity</h2>
The other equations do not fulfill the condition:
2)
>>>>>>>This is not logic
3)
>>>>>>>This is not logic
4)
>>>>>>>This is not logic
Answer:
Step-by-step explanation:
360 + 3*180 = -360 + 540 = 180
For four sides -360 + 180*4 = 360
n-2)*180
For a fifteen sided share the sum of angles = (15-2)*180 = 13*180
Answer:
D is the true statement
Step-by-step explanation:
A
h(4)=13 and h(20)=13, so h(4)=h(20) and it is not true that h(4)<h(20)
B
This is untrue as we can see that the graph reaches its peak at h(12), so it would be symmetric about the line t=12, not t=10.
C
This is untrue as for all values of t less than 24, the height above the ground, h(t), is greater than zero.
D
This is true because as we can see from the table, when t values are equal distances from 12 (eg. 8 and 16), their h(t) values are the same.
