Answer:
x = -6
Step-by-step explanation:
Solve for x over the real numbers:
2 x^2 + 24 x + 72 = 0
Divide both sides by 2:
x^2 + 12 x + 36 = 0
Write the left hand side as a square:
(x + 6)^2 = 0
Take the square root of both sides:
x + 6 = 0
Subtract 6 from both sides:
Answer: x = -6

To find the percentage of cookies baked by Jenny we first have to know how many cookies total there were. 15+18+17=50 cookies all together. The question is asking us "what percentage" (x) "of" (multiply) 50 "is" (equals) 15? Using the variables and numbers only our questiion becomes 50x = 15. Divide both sides by 50 to get x = .3. Since this value is a percentage, we find that percentage by multiplying by 100. 30%.
