Use distribution to find the answer to this one.
5x * 6x² = 30x^3
5x * 3x = 15x²
5x * 7 = 35x
-1 * 6x² = -6x²
-1 * 3x = -3x
-1 * 7 = -7
30x^3 + 15x² + 35x - 6x² - 3x - 7 → simplify this using like terms (look at the exponent of x and if there even is one)
30x^3 stays becuase there is no other like terms
15x² - 6x² = 9x² becuase they are like terms
35x - 3x = 32x because they are like terms
-7 stays because ther is no other like terms
Put these together in the final answer: 30x^3 + 9x² + 32x - 7
Hope this helps!
Answer:
Anthony teaches a pottery painting class in order to save up money for a nice
bike. In yesterday's class, 5 of the 11 students painted piggy banks.
If Anthony randomly chose 4 of the pieces of pottery to glaze, fire, and set on
the top shelf in a certain order, what is the probability that just the first 2 of the
chosen pieces of pottery are piggy banks?
Answer:
10
Step-by-step explanation:
10 workers working 2 hours a day is 2*10=20 work hours per day
2 workers working 5 hours a day is 2 *5=10 work hours per day
Per day 1/2 as many work hours so will take 2 times as long.
5*2 = 10 days
Answer:
The expression is 100x + 50y ≤ 800.
Step-by-step explanation:
The hip hop DJ charge for $100 per hour. Let x be number of hours of hip hop :
For rap DJ, the charge is $50 per hour. Let y be the number of hours of rap :
Given that both DJs spend a maximum of $800. So the final expression is :
The speed that lisa drive was a possibility of 65 mph
