Answer:
x = -1 or x = 7
Step-by-step explanation:
From my understanding, y will be zero and you have to find the value of x.
Step 1: Middle term break
y = x² + 6x - 7
x² + 6x - 7 = 0
x² - 7x + x - 7 = 0
Step 2: Solve
x(x-7) + 1(x-7) = 0
(x+1) (x-7) = 0
x = -1 or x = 7
Therefore, the value of x is either -1 or 7.

Answer: 76%
The fraction of questions Emerson has completed is 19/25. To convert this to a percentage, we want to write this as something divided by 100. To do so, multiply the numerator and denominator by 4, to get the fraction 76/100. Therefore, Emerson has completed 76% of the homework questions.
If you have access to a calculator, a more efficient way to solve such a question would be to convert 19/25 to a decimal (it is equal to 0.76), and multiply by 100 to get 76%.
