- 10 + SQRT(x + 8) = - 4


Radical Equatiion Entered:

- 10 + SQRT(x + 8) = - 4

Step by step Solution 1:
Isolate the square root on the left hands side.

Original Equation:  
- 10 + SQRT(x + 8) = - 4

Isolate: SQRT(x + 8) = 10 - 4


Tidy up:
SQRT (x + 8) = 6


Step 2: Eliminate the radical on the left hand sied:

Raise both sides to the Second Power:

(SQRT X + 8)^2 = (6)^2


After Squaring
X + 8 = 36


Step 3: Solve Linear equation:

Rearrange Equation:
x - 28 = 0

Add 28 to both sides:
x = 28


Possible solution is:

X = 28


Step 4 CHECK:

Original equation, root isolated, after tidy up.

SQRT(x + 8) = 6

Plug in 28 for X
SQRT(28) + 8 = 6

Simplify:
SQRT(36) = 6


Solution Check is
X = 28

Answer: 
(A.);  X = 28

The dimensions of a gymnastic floor are 40 ft by 40 ft. the performance floor is 1 ft less, or 39 ft, per side.
Mashutka [201]

Answer:

the square root of 3200

Step-by-step explanation:

I'm not sure if this is right, because the format of the question wasn't clear, but it sounded like we have to find the diagonal distance of the room from one corner to the opposite. If the sides are 40ft long on both sides, we can use the Pythagorean Theorem to solve this:

40^2+40^2=c^2

1600+1600=c^2

3200=c^2

c=sqrt(3200)

or about 56.5

Can anyone see now? <br> I really need help

3. Yes the cost of each item is proportional because in each pack each t-shirt cost $2.33. You can check that by dividing the amount of money each pack cost by the amount of shirts in each pack. For example the pack of 3 is $7, so 7/3 = $2.33. The pack of 5 cost $11.65, so 11.65/5 = $2.33. And the pack of 7 cost $16.31, so 16.31/7 = $2.33

4) Yes, it is proportional because each x is being squared or multiplied by it’s self.

Please help me out on this question
Mariulka [41]

At x=2, y=4

At x=4, y=16

So the total change in y from x=2 to x=4 is 16-4=12

And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6

Hope that helps. Let me know if you have any questions.
