No because when you variables (with exponents) you add the exponents together.
x^3 • x^3 • x^3 = x^(3+3+3) = x^9
Let’s plug in a number for x to make sure this is correct.
x = 2
2^3 • 2^3 • 2^3 = 8 • 8 • 8 = 512
2^9 = 512

Answer:

11.31 ft

Step-by-step explanation:

Here in this problem ladder forms a right triangle with the wall of the house and it is acts as hypotenuse, length of one leg of right triangle given to be 4 feet.

Let the ladder reaches x ft height of the house.

Hence, by Pythagoras theorem:

${12}^{2} = {4}^{2} + {x}^{2} \\ 144 = 16 + {x}^{2} \\ {x}^{2} = 144 - 16 \\ {x}^{2} = 128 \\ x = \sqrt{128} \\ x = 11.3137085 \\ x = 11.31 \: ft$

Hence, the ladder reaches 11.31 ft height of the house.

Find the value of x.. is the answer 103? if not how do you figure it our

scoundrel [369]

The angle diagonal to 103° is equal to 103°. So here's your equation:

(103+14x+7)°=180°

So now you can simplify:

110°+14x=180°

now subtract 110 on both sides

14x=70°

now divide by 14 on both sides

so the answer is x=5°

hope this helps
