EASY geometry!!
Please help I’ve been stuck on this for too long and it’s due tomorrow :(
1 answer:
Answer:
{n*(n+1) } /2
Step-by-step explanation:
The clearest pattern is that the last digit is multiplied by the number after it and then the multiplication is divided by 2.
1 is multiplied by 2, then divided by 2.
2 is multiplied by 3, then divided by 2.
3 is multiplied by 4, then divided by 2.
So, the pattern is:
{n*(n+1) }/2.
Hope this helped!

f(x) - g(x)
2.5e - 0.04x - 1.2 + 0.2
0.16x + 5.59570457
2t + 8 ≥ -4t - 4
2t+4t ≥ -8-4
6t ≥-12
t ≥ -12/6
t ≥ -2
10mm to cm
1mm is 0.1cm
So 10 MN is 1cm

Remember, you can always plug it in to y= if you have a graphing calculator/the app desmos!
