A total of 443,818 students at 699 community colleges in 48 states completed the Community College Survey of Student Engagement (CCSSE) between 2009 and 2011. About half (52%) of students reported that they “often” or “very often” work harder than they thought they could to meet an instructor’s standards or expectations. Which of the following is a true statement?

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
