Answer:
its C
Step-by-step explanation:
3!, or 1*2*3, or 6. Thus is answered by the factorial function (!)
N is going to be the term u want to find
the formula : an = a1 + (n-1)d.....a1 is going to be ur first term...so ur first term is -3.....or u can find it by subbing in 0 for n
4th term...n = 4
a4 = -3 + (4-1) * -2.2
a4 = -3 + 3(-2.2)
a4 = -3 - 6.6
a4 = -9.6 <== 4th term
tenth term....n = 10
a10 = -3 + (10 - 1) * -2.2
a10 = -3 + 9(-2.2)
a10 = -3 - 19.8
a10 = -22.8 <== 10th term
Answer:
1310
Step-by-step explanation:
Because, you have to add the biggest number which is 380, to the second to biggest number which is 360, which will both get you to 740. Then you have to add the 740 to 300 which both gives you 1040 and then last but not least you have to add, 1040 and 270 together which will give you 1310 and that's your answer. :)
The 2 triangles in the big triangle are similar so we can write
3x / 3x - 2 = 5x / 3x
9x^2 = 15x^2 - 10x
6x^2 - 10x = 0
x(6x - 10) = 0
x= 0 or 5/3
