Answer:The answer will be 2x
Step-by-step explanation:
The correct answers are:
Explanation:
Since she is adding two more jumps every time she goes down hill, this is an arithmetic sequence. The general form of an arithmetic sequence is
Since we want the number of jumps on her 4th through 12th trips, we will set n in the summation from 4 to 12. n=4 goes at the bottom of Σ and 12 goes at the top, to represent the values we are interested in.
Beside this, we write our general form. The first term is 6 and d, the common difference, is 2. This gives us 6+2(n-1) beside the summation:
To evaluate this, we substitute the values 4, 5, 6, 7, 8, 9, 10, 11 and 12 in for n, adding all of the values together:
6+2(4-1)+6+2(5-1)+6+2(6-1)+6+2(7-1)+6+2(8-1)+6+2(9-1)+6+2(10-1)+6+2(11-1)+6+2(12-1)
=6+6+6+8+6+10+6+12+6+14+6+16+6+18+6+20+6+22
=180
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
If the factored form is given by
Then its standard form will be given by
if factored form is given by
Then its standard form will be given by
Hence, only first option is correct.
Answer:
Factored form: (3x-4)(x+2)
Standard form: 3x^2+2x-8
Step-by-step explanation:
3x(x+2)-4(x+2)=(3x-4)(x+2)
3x(x+2)-4(x+2)=(3x^2+6x)-(4x+8)
=3x^2+6x-4x-8
=3x^2+2x-8
