Answer:
43ft
Step-by-step explanation:
<em>side a = x ft</em>
<em>side b = 10 ft</em>
<em>side c = 18 ft</em>
x = 14.967
rounds to = 15
10 + 18 + 15 = 43
<u>43 ft of fence needed</u>
The interval notation given to us means that x is between negative infinity and 5, excluding both endpoints.
So we can write 
which shortens to 
The graph will have an open hole at 5 on the number line, and shading to the left to indicate all points smaller than 5.
Answer:
10 degrees
Step-by-step explanation:
1.) every triangle has angles that add up to 180 degrees
2.) a right triangle has a right angle and two acute angles
3.) right=90 degrees; acute=<90 degrees
4.) 90+80=170
5.) 180-170=10
Answer:
1: 75 degrees
2: 112 degrees
3: 125 degrees
4: 67 degrees

Answer:
c) The given expression represents Addition Property of Equality.
Step-by-step explanation:
Here, the given expression is j = k
Now by ADDITION PROPERTY OF EQUALITY:
The property that states that if you add the same number to both sides of an equation, the sides remain equal.
So, <u> if A = B ⇒ A + </u><u>x </u><u> = B + </u><u>x</u>
<u></u>
Now, here given that j = k
If we add the same number 9 on both the sides, the equation remains undisturbed.
⇒ j + 9 = k + 9
Hence, the above expression represents Addition Property of Equality.
