Answer:
2m
Step-by-step explanation:
(m+3) (m-1)
We need to FOIL
first m*m = m^2
outer -1*m = -m
inner = 3m
last 3*-1 = -3
Add these together
m^2 -m +3m -3
m^2 +2m -3
Answer:
The answer is -29
Step-by-step explanation:
All you have to do is plug -4 where m is and -8 where n is. Your equation would look like this... 3-(-4)(-8). Then all you have to do is plug it into your calculator and you will get -29.
The temperature at midnight would be -14*F. Subtract 10 from -4 and you get -14*F
Answer: Phillip is correct. The triangles are <u>not </u>congruent.
How do we know this? Because triangle ABC has the 15 inch side between the two angles 50 and 60 degrees. The other triangle must have the same set up (just with different letters XYZ). This isn't the case. The 15 inch side for triangle XYZ is between the 50 and 70 degree angle.
This mismatch means we cannot use the "S" in the ASA or AAS simply because we don't have a proper corresponding pair of sides. If we knew AB, BC, XZ or YZ, then we might be able to use ASA or AAS.
At this point, there isn't enough information. So that means John and Mary are incorrect, leaving Phillip to be correct by default.
Note: Phillip may be wrong and the triangles could be congruent, but again, we don't have enough info. If there was an answer choice simply saying "there isn't enough info to say either if the triangles are congruent or not", then this would be the best answer. Unfortunately, it looks like this answer is missing. So what I bolded above is the next best thing.
The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
