Answer:
b and e
Step-by-step explanation:
Answer:
the answer is 5 because 40 divided by 8 is 5
(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)
Well u need to give me the equation and the substitutions for the variables then I can solve it
