Answer:
is a trinomial having with:
Step-by-step explanation:
Considering the trinomial
- Any polynomial with 3 terms is a trinomial, so it is a trinomial.
It is clear that '5' is the highest power of the 'x' variable. so, the polynomial has a degree of 5.
'3' is the constant term. The reason is that any term with no variable is called a 'constant' term. So, '3' is the constant term.
Therefore, is a trinomial having with:
Answer:
5:1
Step-by-step explanation:
30:6 divided by 6 is 5:1
Answer:
the cost of one sweater is $40
Step-by-step explanation:
The computation of the cost of the one sweater is shown below;
Let us assume the sweater be x
And, the pant be y
Now the equations are
2x + y = $120 ..............(1)
x + 2y = $120................(2)
Now multiply by 2 in equation 1
4x + 2y = $240
x + 2y = $120
3x = $120
x = $40
Hence, the cost of one sweater is $40
3(9)+2(6)=
multiply 3•9=27
multiply 2•6=12
27+12=39
