15+(10-x)=15 would be your equation if that is what you are looking for.
Answer:
52 degrees.
Step-by-step explanation:
(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)
just add them up. ans:14 1/4 pounds
It would be 6 haha I just took a test and got it right
