2. A triangle has sides of lengths 15, 23, and 28. Is it a right triangle? Explain. A. No; 152 + 232 = 282
C. Yes; 152 + 232 + 282
B. No; 152 + 232 282
D. Yes; 152 + 232 = 282

Which inequality comparing two of the expressions is true when 0.7 < x < 0.9

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103

Look at this pattern ; 1,4,9, number 10000 belongs in this pattern . what’s the place of this number?
