Answer:
Yes, Fiona is correct
Step-by-step explanation:
WHen the pythagorean theorem is applied to the side lengths (2^2 + 4^2 = c^2), the result for c^2 is 20. The correct answer would be sqrt.20. But Fiona is also correct becuase sqrt of 20 can be simplified to sqrt.4 * sqrt.5; which equals 2*sqrt.5
G. 36 people. There were only 36 people choose documentaries.
Answer:
you are 18
Step-by-step explanation:
10-7=3
3*6=18
or backwards,
18*1/6=3
3+7=10
4.2.
If the 2 inch side was scaled to 10.5 inches the 5 inch side would be scaled by 10.5/2 = 5.25, so would be 25.125 inches which is too big.
So the 10.5 inches is the 5 inch side on the original, and so it 10.5/5 = 2.1 times bigger.
Therefore the smaller side would be 2*2.1/= 4.2 inches.
Answer:
no solutions.
Step-by-step explanation:
2x - 3y = 1
-4x + 6y = -4
Simplifying our second equation, we get:
-4x + 6y. =-4
-2x + 3y = -2
2x - 3y = 2
From here, we can see that this system of equationis has no solutions because, how can 2x - 3y be equal to both 1, and 2???
