C. Exponential. Because the numbers are neither constant nor increasing and decreasing.
The thousands place is <u /><em></em>the 9 in 39<u>9</u>,713. 7 is closer to 10 than to 0, therefore, you roundup, increasing the thousands place by one. Carry the 0 to the next 9 in the ten thousands place, and again to the hundred thousands, adding one to the 3. Therefore the answer is 400,000.<u />
Answer:
3131x+1
Step-by-step explanation:
Make equation simple
5x times 5x times 5x times 5x times 5x +x+1
Solve
5 times 5 times 5 times 5 times 5 = 3125
x times x times x times x times x times x = 5x
3125+5x=3130x
Now you might be thinking you cant add x but here your can because it is just broken apart
now add x+1
3131x+1
