VashaNatasha [74]

Answer:

469.9 ft^2

Step-by-step explanation:

The rate at which soil covers the garden is:

                     

  125.3 ft^2  /  (1 bag)

If Stephanie has 3 3/4 bags of soil to start with, the area she can cover with this soil is (rate)(number):

   125.3 ft^2          15 bags

------------------- * ---------------- = 469.9 ft^2 can be covered with 3 3/4 bags

        1 bag                  4

In simplest radical form, what are the solutions to the quadratic equation 6 = x2 - 10/?
pickupchik [31]

Answer:

x = 5 \± \sqrt{31}

Step-by-step explanation:

Given

6 = x^2 - 10x

Required

The solution in radical form

6 = x^2 - 10x

Rewrite as:

x^2 - 10x - 6 = 0

Using the quadratic formula, we have:

x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}

Where

a = 1

b = -10

c = -6

So, we have:

x = \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*(-6)}}{2*1}

x = \frac{10 \± \sqrt{100 +24}}{2*1}

x = \frac{10 \± \sqrt{124}}{2}

Split the roots

x = \frac{10 \± \sqrt{4 * 31}}{2}

Express \sqrt 4 as 2

x = \frac{10 \± 2\sqrt{31}}{2}

Split the fraction

x = \frac{10}{2} \± \frac{2\sqrt{31}}{2}

x = 5 \± \sqrt{31}

Here is an easy one
kvv77 [185]
Remember that the angles of a triangle is 180 so:

(7x+8) + (5x+2) + (7x-1) = 180
7x+8+5x+2+7x-1=180
7x+5x+7x=180-8-2+1
19x=171
X= 171/19
X=9

Therefore x=9
