The base of a 13 foot ladder is 5 feet away from the wall. How far up the wall does the ladder reach? A)8 feet B)10 feet C)12 fe

Lisa [10]

You are solving for the height. Use the formula:

c² - b² = a² in which c = hypotenuse

(13)² - (5)² = a²

Simplify

169 - 25 = a²

144 = a²

Isolate the a. Root both sides

√144 = √a²

a = √144

a = √(12 x 12)

a = 12

C) 12 feet is your answer

Help, i know the answer but i don’t know how to do the work

Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying each radical before combining them.

$\sqrt{45t}$

= $\sqrt{9(5t)}$

= $\sqrt{9}$ × $\sqrt{5t}$ = 3 $\sqrt{5t}$

-----------------------------------------------------------------------------

$\sqrt{125t}$

= $\sqrt{25(5t)}$

= $\sqrt{25}$ × $\sqrt{5t}$ = 5 $\sqrt{5t}$

---------------------------------------------------------------------------

Hence

2(3 $\sqrt{5t}$ ) - 3(5 $\sqrt{5t}$

= 6 $\sqrt{5t}$ - 15 $\sqrt{5t}$

= - 9 $\sqrt{5t}$ → C
