The ladder and the wall form a right triangle.
The length is the hypotenuse = 15.
The base = 2*(15/5) = 2*3 = 6

Use pythagorean theorem to find other side of triangle:
a^2 + b^2 = c^2 \\  \\ a^2 + 6^2 = 15^2 \\  \\ a^2 + 36 = 225 \\  \\ a^2 = 189 \\  \\ a = \sqrt{189} = 3 \sqrt{21}

Find the sum. Write your answer in simplest form. 3/7 + 2/3​
Delicious77 [7]

Answer:

1 2/21

Step-by-step explanation:

We start out with:

3/7 + 2/3

In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:

3/21 + 2/21

But what about the numerators? You do the same thing as before (multiplying by the other's denominator).  Now we have:

9/21 + 14/21

We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:

1 2/21!

?what is the answer??????
Ierofanga [76]

Answer:

nx^(n-1).

Step-by-step explanation:

d/dx (x^n)

We multiply by n than subtract 1 from the exponent (n):

= n x^(n-1)

Numerical examples:

d(x^3) dx = 3 * x^(3-1)

= 3x^2.

d(2x^5)/dx = 5*2 x^(5-1)

= 10x^4.
