The answer would be the first choice. 
Explanation: The reason for this is that the question was pretty much just asking what the area of the resulting two-dimensional cross section would be -the shape in gray- (which can be found by using the formula 
. To add on, since the dimensions of the shape are already given (5 and 3) all you've to do is multiply: 3*5=15
That's how you get to the answer.
To do that you do 6*3=18 and then you have 18(x+2) To find X we distribute the 18
18x + 36 is what is left
Hope that helped:)
Answer:
56 m
Step-by-step explanation:
The area of a rectangle is found by multiplying length by width. since we already know the length, then we can just divide the total area by the length to find the width.
5432/97 = 56
and to check our work, make sure to multiply length by width.
97 * 56 = 5432
Th equation would be y=6x. Bruce unloads 6 boxes in 1 minute, so that would be your unit rate. X represents how many minutes he takes to unload the boxes, so for each minute Bruce unloads 6 boxes.
