Answer:
The answer to your question is below
Step-by-step explanation:
A) 2x > -6
x > -6/2
x > -3
It must be a graph with an open circle starting at -3 and then to the right.
It is the first graph.
B) x - 4 < -7
x < -7 + 4
x < -3
The graph must be an open circle starting at -3 and pointing to the left.
it is the second graph.
C) 6 + x ≤ 3
x ≤ -6 + 3
x ≤ -3
The graph must be a closed circle starting at -3 and pointing to the left.
it is the forth graph.
D) -x - 5 ≤ -2
-x ≤ -2 + 5
- x ≤ 3
x ≥ -3
The graph must be a closed circle starting at -3 and pointing to the right.
It is the third graph.
Answer:
a) 
b) 
Step-by-step explanation:
a) the exponent is 2, therefore the value of ![\sqrt[2]{9}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B9%7D)
would go in the place of the base.
b) the exponent is 2, therefore the value of ![\sqrt[2]{\frac{16}{25} }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7B16%7D%7B25%7D%20%7D)
would go in the place of the base => 
=

Answer:
Perimeter = 180
Area = 1080
Step-by-step explanation:
Perimeter is length of all sides added together. 30+78+72 = 180
Area is the length times the height/2 for a triangle. 30*72/2 = 1080
I hope this helped <3
