Answer:
4cm
Step-by-step explanation:
Firstly, we need to know the perimeter of the rectangle so as to know the length used to make the rectangle. This is 2(l + b)
P = 2(12 + 6) = 2(18) = 36cm
The length remaining to make the hexagon would be 60 - 36 = 24cm
Now since the hexagon is regular, the length of each side would be 24/6 = 4cm
Note: hexagon is a polygon with 6 sides
The blanks are as follows:
- Angle addition postulate
- Subtraction property of equality
- Corresponding sides of similar triangles are proportional
- Multiplication property of equality
Answer:
Step-by-step explanation:
What we have is a general equation that says this in words:
Laura's hours + Doug's hours = 250 total hours
Since we don't know either person's number of hours, AND since we can only have 1 unknown in a single equation, we need to write Laura's hours in terms of Doug's, or Doug's hours in terms of Laura's. We are told that Doug spent Laura's hours plus another 40 in the lab, so let's call Laura's hours "x". That makes Doug's hours "x + 40". Now we can write our general equation in terms of x:
x + x + 40 = 250 and
2x = 210 so
x = 105
Since Laura is x, she worked 105 hours in the lab and Doug worked 40 hours beyond what Laura worked. Doug worked 145. As long as those 2 numbers add up to 250, we did the job correctly. 105 + 145 = 250? I believe it does!!
