White raven [17]

<u>Answer:</u>

The height of the ladder is 14.491 feet

<u>Explanation</u>:

Given the height is 11 feet

Base = 7 + 2 = 9 feet

Consider the ladder to be the hypotenuse

Applying Pythagoras Theorem,  

H^2   = P^2 + B^2

Substituting the values in the above formula,

H^2  = 112 + 92

H^2  = 121 + 81

H^2 = 210

H = sqrt(210)

H = 14.491

Therefore, the height of the ladder is 14.491 feet

-5+7q+ -5q+ -9q please help
vekshin1

For this case we must simplify the following expression

-5 + 7q + (- 5q) + (- 9q)

We know that, by definition:

+ * - = -

So, rewriting the expression we have:

-5 + 7q-5q-9q =

We add similar terms taking into account that:

  • Equal signs are added and the same sign is placed.
  • Different signs are subtracted and the major's sign is placed:

-5 + 2q-9q =\\-5-7q

Answer:

-5-7q
