Can somebody help I am really bad at this

40 feet

Step-by-step explanation:

4+4+8+4+12+8

= 40 ft.

d. 40

Step-by-step explanation:

4 + 4 + 8 + 4 + 12 + 8 = 40

bottom: top 4 and 8 = 12

side: side 4s = 8

uh i hope that makes sense

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
