Answer:

The equation has no solution.

Step-by-step explanation:

Hi there!

First, let´s write the equation:

(√x + 3) + 6 = 3

To solve the equation, let´s subtract 6 to both sides of the equation:

√x + 3 = -3

subtract 3 to both sides of the equation:

√x = -6  (the square root of any number can´t be negative, but let´s solve it anyway and then check the solution).

Square both sides of the equation:

x = 36

Now, let´s check the solution:

(√x + 3) + 6 = 3

x = 36

(√36 + 3) + 6 = 3

(6 + 3) + 6 = 3

9 + 6 = 3

15 ≠ 3

Then, the equation has no solution.

Have a nice day!

Answer:

129 square foot

Step-by-step explanation:

<u>Step 1: Convert height of the door to inches</u>

Height of the door = 10 feet 8 inches

1 feet = 12 inches

10 feet = y inches

<em>Cross Multiply</em>

y = 120 inches

Height of door in inches = 120 + 8 =128 inches

<u>Step 2: Find the surface area of one side of the door</u>

Surface area = length x width

length = 128 inches

width = 145 inches

Surface area = 128 x 145

Surface area = 18560 inches

<u>Step 3: Convert surface area from inches to square foot</u>

Surface area = 18560 inches

1 square foot = 144 inches

         y           = 18560 inches

<em>Cross multiply</em>

144y = 18560

y = 18560/144

y = 128.89 rounded off to 129 square foot.

Therefore, you should report 129 square foot surface area to the hardware store.

Solve the differential equation dy/dx = (x-2) / (y-2)
Brums [2.3K]

Answer:

y = 2 ± \sqrt{x^2 - 4x + 4 + C}

Step-by-step explanation:

Solve using separable equations

First put x and dx on the same side and do the same for y

(y-2)dy = (x-2)dx

Now you can integrate

\frac{x^2}{2} +2x + C1 = \frac{y^2}{2} +2y\\ + C1

Now we depending on how what ur instructor wants you may need to give exact solutions. We can do this by solving he quadratic equation for Y

Doing this you get:

y = 2 ± \sqrt{x^2 - 4x + 4 + C}

<em>Note C's were simplified.</em>
