Answer:

x = 5 ± \sqrt{17}

Step-by-step explanation:

Given

x² - 10x + 25 = 17 ← left side is a perfect square, thus

(x - 5)² = 17 ( take the square root of both sides )

x - 5 = ± \sqrt{17} ( add 5 to both sides )

x = 5 ± \sqrt{17}

Thus

x = 5 - \sqrt{17}

x = 5 + \sqrt{17}

Write 13 divided by 4/7 as a multiplication expression
almond37 [142]

Answer:

13/1*7/4

Step-by-step explanation:

The way you get this is by using the Keep, Change, Flip Method. 13 as a fraction would be 13/1, and this is the keep phase. The change phase is where you change division to multiplication. The flip phase is when we flip the numerator and denominator. Remember, this only works when dividing fractions.
