Answer:
x^2+11x+10
or
(x+1)(x+10) since you can factor x^2+11x+10
Step-by-step explanation:
Let's do synthetic division.
We are dividing by x+2, so -2 will be on the outside. Like this:
-2 | 1 13 32 20
| -2 -22 -20
|___________________________
1 11 10 0
The remainder is 0, so (x+2) is indeed a factor of x^3+13x^2+32x+20.
The other factor we found by doing this is (x^2+11x+10).
You can find more factors by factoring x^2+11x+10.
Two numbers that multiply to be 10 and add to be 11 is 10 and 1 so the factored form of x^2+11x+10 is (x+10)(x+1).
The mean is the best measure to summarise the scores.
The answer is C)i, ii, iii, iv
To solve for x, we need to get it on one side by itself, and then to make sure we are left with ONLY x, no coefficients or anything.
-2x -3 > 97.
Add 3 to both sides.
-2x > 100.
Divide both sides by -2 (remember to flip the inequality when dealing with negatives).
x < -50
I hope this helps!
