a) 5x+30
you can factor out 5
5( x+6)
b) 2x^6 -12x^2
the GCF is 2x^2
2x^2 (x^4 -6)
(remember when factoring out the x^2 from x^6 you subtract the exponents
Answer:
B
Step-by-step explanation:
quantity eleven times y = 11y.
quantity three times x = 3x.
the first one over the second one would be 11y/3x, and B is the answer that shows this.
A die is rolled and the results are 1, 2, 1, 4, 5, 6, 1, 3, 6, 6, 5, 2, 3.

Answer: True</h3>
We have A = 2 copies of "2" showing up out of B = 13 rolls total
A/B = 2/13 = 0.1538 is the experimental probability of rolling a 2
Compare this with 1/6 which is the theoretical probability of rolling a 2 (since there is one side labeled "2" out of 6 sides total)
1/6 = 0.167 approximately
Comparing 0.1538 with 0.167 is fairly close
or you could argue that 2/13 is close to 2/12 = 1/6
The Mechanic that worked for 20 hours charged $95 per hour. 95 times 20 = $1900
The Mechanic that worked for 5 hours charged $80 per hour. 80 times 5 =400
400+1900= $2300
