Answer:
The answer is 1
Step-by-step explanation:
Formula for finding the slope: 
Take y2 and y1 from (4,<u>4</u>) (1,<u>1</u>)
Take x2 and x1 from (<u>4</u>,4) (<u>1</u>,1)

This is how the answer is 1
Hope it helps :)
-1.1 should be the right answer
According to PEMDAS, you would look in the parenthesis first. In the first set of parenthesis we have an exponent. 10x10x10x10 is 10,000. Then we multiply this by 2.5. We now have 25,000. We put this to the side..
Next, we do the same thing on the other side -- 10x10x10 is 1,000 and then you multiply that answer by 1.5 and we have 1,500. Now we can subtract. 25,000 - 1500 = 23,500 :)
<span>So the question is how to find the volume of a L-block geometrical body. To do that we need to turn an L-block into something we know how to calculate the volume. in the case of an L-block we can use two rectangles because we can calculate it's volume easily, as V=a*b*c and simply sum the two volumes. </span>
