Step-by-step explanation:
2)
80 +67 +97+ 98 +85 +72 = 499
499/6=83.1666666667
Average: 83.1666666667
3)
a) <em>97</em> <u>93</u> 92 90 90 <u>90</u> <em>86</em> =90
median of Edgars grades for his midterm is 90
<em>99</em> <u>93</u> 93 89 88 <u>88</u> <em>86</em>
median of Edgars grades for his trimester is 89
7)
(z+9+18)= z+27 (remember don't mix the numbers if they are attached to the x)
(z+18+9)= z+27 (because adding is both ways the same)
a) a + b =b + a
Geometry
1.
a) 6x^2
b)The surface area of a cube = 6a^2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, x is just the length of one side of a cube
c) The unit would be sq(squared) feet
The interval notation that defines this set is: (-∞, -5]
And the graph can be seen below.

How to graph the inequality?</h3>
Here we want to graph the inequality:
x ≤ -5
This refers to all the values of x equal or smaller than -5.
To graph this, we need to graph a closed circle at -5, and we need to draw an arrow that points to the left (values smaller than -5). The graph is the one that you can see below.
The interval notation that defines this set is: (-∞, -5]
The first end is open, and the second is closed (because of the symbol ≤).

Step-by-step explanation:
Answer:
no
Step-by-step explanation:
4:12
Divide each by 4
4/4:12/4
1:3
Multiply each by 2
1*2: 3*2
2:6
That is not equal to 2:5
Step-by-step explanation:
Sides of hexagon = 6
Hexagon
1
1 + 5 = 6
1 + 5 + 9 = 15
1 + 5 + 9 + 13 = 27
1 + 5 + 9 + 13 + 17 = 45
