Can you form a right triangle with the three lengths given? Why or why not? 7 in., 24 in., 25 in.

yes; 7 + 24 = 25

no; 72 + 242 ≠ 252

no; 7 + 24 ≠ 25

yes; 72 + 242 = 252

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

Dexter read 11 science fiction books and 5 history books. lena read 9 science fiction books and 4 history books. compare the students’ ratios of science fiction books to history books. 1. determine the ratios’ form:    science fiction books to history books 2. write the ratios as fractions:    dexter: 115; lena: 94 3. rewrite with a common denominator. 4. compare. 5. answer the question. determine which shows the correct comparison of the ratios for this problem.
