TITLE: Real - Life Application of Addition and Subtraction of Polynomials Answer the following problems. Provide an illustration or drawing that supports the given problem. Put your answer in the given sample ornaments.

1.) There are 3x ^ 2 + 7x - 8 boys and 2x ^ 2 - 3x + 9 girls in the class. How many students are there?

2.) Sheila had 5y ^ 2 - 8x + 6 apples. He ate 3y ^ 2 + 5x - 3 of them. How many apples are left?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
