EASY QUESTION WILL GIVE BRAINLIEST

29622 m^2

Step-by-step explanation:

SA = 2 ( lw+ wh+ lh)  where l = length  w = width  h = height

SA = 2 ( 81*75+ 75* 56+ 81*56)

     = 2 (6075+4200+4536)

      = 2(14811)

      29622

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
