2. Use the distance formula to find the lengths of the sides of the second triangle, triangle PQR.

3, 4, 5
13 /10,3
9, 16, 25
3,/13 3/10,9



The answer is B.

Given f(x) = 2x^2- 5x+1, determine the function value f(2). do not f(x) = in your answer

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
