The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression.
a²b(7 + 10b +14b²)
Answer:
2120
Step-by-step explanation:
Answer:
7. 21 times more
8 1/9
Step-by-step explanation:
7. 2 pants, 5 tops , 3 gloves, 7 masks
2*5*3*7 =210 outfits
10 * what = 210
10 *21 = 210
21 times more
8. There are 36 possible outcomes
11 121 131 14 15 16
21 22 23 24 25 26
31 31 33 34 35 <em>36
</em>
41 42 43 44 <em>45</em> 46
51 52 53 <em>54</em> 55 56
61 62 <em>63</em> 64 65 66
There are 36 possibilities and 4 have a sum of 9
P (sum of 9) = outcomes with sum of 9/total
4/36 = 1/9
Answer:
B.-21
C. -3a^2+2a
Step-by-step explanation:
You replace the value in the parentheses for the x:s in the function. For part b you do 3 squared (9) times -3 which is -27. Then you substitute 3 for x in the next term, 2x which gives you 6. Adding -27 and 6 you get -21. Follow the same reasoning for part c and you get a squared times -3 and add to that 3a since you change out the x for the a.
