Answer:
Step-by-step explanation:
Hello! To solve this question, we can write and solve a proportion. Set it up like this: 5,880/x = 42/100. You do this, because you’re looking for the total amount of area there is. Cross multiply the values and you get 588,000 = 42x. Now, divide each side by 42 to isolate the “x”. 588,000/42 is 14,000. x = 14,000. Arizona’s total area is 14,000 square miles.
Answer:
The equation that gave the solution provided is either
x² + 5x + 4 = 0 or k(x² + 5x + 4) = 0 where k = real number
Step-by-step explanation:
Although, the question isn't complete and the blanks to be filled aren't provided, Hence, we can work out a quadratic equation from the solutions for x given
The solutions for x include x = -4 or x = -1
x = -4 or x = -1
(x + 4) = 0 or (x + 1) = 0
So,
(x+4)(x+1) = 0
x² + 4x + x + 4 = 0
x² + 5x + 4 = 0
Hence, the equation that gave this solution is either x² + 5x + 4 = 0 or a constant multiple of the equation obtained; k(x² + 5x + 4) = 0
Hope this Helps!!!
