The answer is -1 , since the numbers cross cancel to make 1/1 and it's a negative multiplied by positive
Here is your graph of y < 3x + 1.
Answer:
72
Step-by-step explanation:
If we look at the smaller triangle, it has side lengths of 31, 36 and 43. Since those measurements are given again on part of the bigger triangle, we can conclude that the smaller triangle has been dilated by a scale factor of 2 to get the bigger triangle. Using this, we can multiply 36 by 2 to get our answer of 72.
Let's use some examples. So what can you make with 16? You can make 1 and 15, 2 and 14, etc.
How about trying 1 and 15 first?
1*15 = 15
What about 2 and 14, 3 and 13, and 4 and 12?
2*14 = 28
3*13 = 39
4*12 = 48.
Now we notice a pattern-- the numbers keep getting bigger, right? So the closer you get to the middle, the bigger the area will get. So if we divide 16 by 2, we get 8. Let's try 8 and 8.
8*8 = 64
That's larger than 48! Now let's try a couple more to make sure.
9*7 = 63
10*6 = 60
11*5 = 55
Next time, you'll know that with one of these problems, the biggest area would be the two numbers closest to each other you can get. Hope this helps! :)
