He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47
Answer:
5 oranges
Step-by-step explanation:
to solve this problem we need to make a cross-multiplication equation
2.34 is to 6 as 1.95 is to ?
? is the number of oranges that are needed to be found that were bought
2.34/6 = 1.95/?
Now we cross multiply 6 and 1.95 = 11.7
11.7/2.34 = 5
Give brainliest, please!
hope this helps :)
Answer:
These two figures are similar because 
equals 
Step-by-step explanation:
The figures will be similar if their ratios of the two sides are equal. So we need to check the ratios of the figures to see if they are similar or not.
For the smaller figure the ratio is , and for the bigger figure the ratio is which upon simplification reduces to .
So we see that the ratios are equal. Thus the figures are similar.
