Answers
13^2=10^2+11^2-2×10×11×cos(°)
169=100+121-220cos(°)
220cos(°)=100+121-169
220cos(°)=52
cos(°)= 13/55
°=cos-1(13/55)
°=76.328°

4s2t – 3st2
a.) The sum is a binomial with a degree of 2.
b.) The sum is a binomial with a degree of 3.
c.) The sum is a trinomial with a degree of 2.
d.) The sum is a trinomial with a degree of 3.
Answers
The statement (b) the sum is a binomial with a degree of 3 is correct.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
We have expressions:
6s²t – 2st²
4s²t – 3st²
Adding the above two expression, we get;
= (6s²t – 2st²) + (4s²t – 3st²)
Combining like terms:
= 10s²t - 5st²
The above expression has degree 3(2+1)
Thus, the statement (b) the sum is a binomial with a degree of 3 is correct.
