The area is 10 just use a area calculator!
(5x+1)² = 7; expand: 25x² + 10x +1 = 7 or 25x² + 10x -6 = 0
Solve this quadratic for x:
x = [-b + √(b² - 4ac)]/2a and x = [-b - √(b² - 4ac)]/2a
Plug the values and you'll find :
x = (- √7 - 1)/5 (answer C)
x = (+√7 -1)/5 (answer E)
Answer: yes you are correct 2 /1/2 is greater
Step-by-step explanation:
9 because it's the gcf (greatest common factor)
-1/4 is not = -1 / 1/4 ( its = -4) so its neither .
