Answer:
ji
Step-by-step explanation:
Like terms have the same variable and power. The sum of the two polynomials
is
.
<h3>What are Like terms?</h3>
Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
We know that in order to find the sum of the two polynomials we need to add or subtract the like terms, therefore, the sum of the polynomials can be done as,

Hence, the sum of the two polynomials
is

Answer:
15%
Step-by-step explanation:
Ok so if you have to get rid of 25% of 16 than thats 12 because 4 quarters is 100 than you have to think how much does he have know which is 75% so three more types of birds adds 15% and 75 + 15= 90 and the increase was 15% so The answer is 15%
Answer:
39
Step-by-step explanation:
The angle marked 39 degrees and <2 are vertical angles and vertical angles are equal. This means that <2 = 39 degrees
To find if it's a right triangle, we use the Pythagorean Theorem of a² + b² = c² where a and b are the legs of the triangle (the shorter measurements) and c is the hypotenuse (the biggest measurement).
28² + 34² = 43²
784 + 1156 = 1849
1940 ≠ 1849
No. This is not a right triangle. The sum of the squares of the shorter measurements (AKA the legs) do not equal the square of the biggest measurement.
