Answer:

20.1\ \text{feet}

Step-by-step explanation:

The given relation is

5x^2-2025=0

where x is the portion of walkway in which the person walks

Rearranging the equation we get

5x^2=2025\\\Rightarrow x^2=\dfrac{2025}{5}\\\Rightarrow x^2=405\\\Rightarrow x=\sqrt{405}\\\Rightarrow x=20.124\approx 20.1\ \text{feet}

The length of the portion of the walkway labeled x is 20.1\ \text{feet}.

Answer:

3, 4, and 5

Step-by-step explanation:

To put it simply, 3 + 4 + 5 = 12 and the numbers are consecutive, next to each other.

The method:

The three consecutive numbers could be called x, x + 1, and x + 2 and we know that x + x + 1 + x + 2 = 12

This can be simplified to 3x + 3 = 12. Next, subtract 3 from both sides to get 3x = 9. Now, divide both sides by 3 to get x = 3.

This means that the first number is 3 and the other numbers are 4 (3 + 1) and 5 (3 + 2).

Hope this helps!

How do I evaluate 2x to the 4 power + 2x to the 3 power when x = 7
lutik1710 [3]
First, you want to multiply 2 times 7 which is 14 then do 14 to the 4th power which is 38,416, then add that by 14 to the third power which is 2,744, so then you will get 41,160 which is your answer.
