Type the correct answer in each box. use numerals instead of words. consider this quadratic equation. x2 + 2x + 7 = 21 the number of positive solutions to this equation is . the approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is .

Step-by-step explanation:

The given expression is

x^{2}+2x+7=21

To solve this expression, we need to pass all terms to the left side

Now, we solve the equation using the quadratic formula

Where

Replacing these values, we have

Therefore, this quadratic equation has only 1 positive solution, and the greatest solution is 2.87, rounded to the nearest hundredth.

47 - 90 = 43

43 - 180 = x

x = 137
