She has 8 nickles and 16 dimes. 8 * .05 = .40 and 16 * .10= 1.60... 1.60+.40 =2.00 :)
The slope would be 2. Rise over run remember that.
Answer:
multiply 343 by 2 and then divide that number by 3. the answer is 228.666666666
The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.
x^3+5x^2-6x-30
(x^3+5x^2)+(-6x-30)
x^2(x+5)+(-6x-30)
x^2(x+5)-6(x+5)
(x^2-6)(x+5)
-------------
Answer: (x^2-6)(x+5)
