Answer:
Option b). The sum is a binomial with a degree of 3.
Step-by-step explanation:
The given polynomials are,
1). 6s²t – 2st²
2). 4s²t – 3st²
<u>Sum of polynomials</u>
Sum = (6s²t – 2st²
) + (4s²t – 3st²)
Sum = 6s²t + 4s²t - 2st² - 3st²
Sum = 10s²t - 5st²
degree = 2 + 1 = 3
It is a binomial with degree of 3.
Therefore the correct answer is option b).The sum is a binomial with a degree of 3.
Answer:
The ratio of number of purple beads to the number of pink beads is: 15:31
Step-by-step explanation:
Number of pink beads = 31
Number of Purple beads = 15
We need to find ratio of number of purple beads to the number of pink beads
So, The ratio of number of purple beads to the number of pink beads is:
Number of purple beads : Number of pink beads
15 : 31
Since it cannot be simplified further, So
The ratio of number of purple beads to the number of pink beads is: 15:31
Answer:
$6.75 dollars
Step-by-step explanation:
Answer: 1h and 25min
To find how long you can drive in a minute we do 48 divided by 32 = 1.5. So it takes 1 min to drive 1.5km
Then we 146 divided by 1.5 = 97 and a third to find out how long it takes to drive 146km.
Then we convert it to hours to get 1h and 57min.
Then we - 32 because we already drove 32min. 1h and 57min - 32 = 1h and 25min
