15 ft 7 inches

Here are the steps to doing this,

1. Write out

    6 ft 10 inches
+  8 ft 9 inches
-------------------------

2. Add the inches first, 10 + 9 = 19
3. Next, add the feet, 

6 + 8 = 14

What you have is 14 feet 19 inches
Hopefully, you know that 12 inches is equivalent to one foot.

4. Subtract 12 from 19, and you get 7.
5. Your answer is 15 feet 7 inches

Hope this helps!

What is the inverse of the function y= x^2-12
aalyn [17]

Answer:

y=\sqrt{x+12}

Step-by-step explanation:

To find the inverse of a function, what I like to do is to switch the places of x and y, and then try to isolate y again like so:

x=y^2-12

x+12=y^2

y=\sqrt{x+12}

Hope this helps!

Hurry 50 points for correct answer
Ad libitum [116K]

Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Step-by-step explanation:

The equation x=\sqrt{6x+7} can be solved by squaring both sides:

x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

1 = \sqrt{-1}\\ 7 = \sqrt{49}

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Find the total surface area of the prism.<br><br> 13 in.<br> 9 in.<br> 15 in.<br><br> Need asap
natta225 [31]

Answer:

The surface area of a rectangular prism with length of

15, a width of 9 and a height of 13 is:

894.0000 square units.

not sure

Step-by-step explanation:

To find the surface area, use this rectangular prism surface area

formula:

Surface Area =

[(Length x Width) + (Length x Height) + (Width x Height)] x 2

Example: The surface area of a rectangular prism with length of

3 inches, width of 4 inches, and height of 5 inches:

Surface Area = [(3 x 4) + (3 x 5) + (4 x 5)] x 2

Calculated out this gives a surface area of 94 Square Inches.
