Your answers should be, the first one 1. (3.1)(3.1)(3.1)(3.1) and 3. (3.1)(3.1)(2)
For the number 2 is -14x+6
For the number 1 is (2,3)
and I hope you that helps you!!!
To get the difference we proceed as follows:
<span>3n^2(n^2+4n-5) - (2n^2-n^4+3)
open the parenthesis
3n</span>²×n²+3n²×4n-3n²×5-2n²+n⁴-3
this will give us:
3n⁴+12n³-15n²-2n²+n⁴-3
putting like terms together
3n⁴+n⁴+12n³-15n²-2n²-3
simplifying further we obtain
4n⁴+12n³-17n²-3
b] The highest degree of the the result will be obtained by considering the term with the highest power. The highest power is 4, thus the result will be classified as polynomial of degree 4.
Answer:
Step-by-step explanation:
x + y = 11
.25x + .05y = 1.15
25x + 5y = 115
-25x - 25y = -275
-20y = -160
y = 8 nickels
x + 8= 11
x = 3 quarters
3 quarters and 8 nickels
