E. 5x^2 - 10= 0; 5(x^2 - 2)= 0; x^2= 2; x = √2
f. x^2 - x=0; x(x -1)= 0; x = 0, x= 1
g. 4x^2 + 4x= 0 ; 4x( x + 1) = 0; x = 0, x = -1
h. -x^2 + x = 0; -x(x - 1)= 0; x = 0, x = 1
Answer:
The price before tax was $110
Step-by-step explanation:
Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b: b + 0.175b = $129.25. Combining the b terms, we get:
1.175b = $129.25. Solving for b by dividing both sides by 1.175, we get
b = $110. The price before tax was $110.

Let x be the total number of questions. We know that Jess answered correctly 35 of them, and those 35 are the 74.47% of all questions.
So, can build the proportion linking the correct answers to the total number of questions:
Solving for x, we have
