NikAS [45]

Answer:

x=5 feet

Step-by-step explanation:

At floor level y=0

If the expression is:

0=1/3(x-5)(x+5)\\0=1/3(x^2-25)\\0=1/3x^2-25/3\\25/3=1/3x^2\\25=x^2\\x=5

But, with the negative sign, the answer is x= 5i (where i is imaginary)

Which of the following best describes the expression 7(y + 5)?
damaskus [11]

Answer: LAST OPTION.

Step-by-step explanation:

To solve this exercise is important to remember the following definitions:

  1. The sum is the result obtained when we solve an addition.
  2. The product is the result obtained when we solve a mutiplication.
  3. Given a multiplication (a)(b)=c, "a" and "b" are factors and "c" is the product.

In this case, you have this expression:

7(y + 5)

Notice that the there is an addition of two terms (y and 5) inside the parentheses.

Outside the parentheses you can notice that the number 7 is multiplying the sum of the terms  mentioned before.

Therefore, you can conclude that the best description for this expression is:

<em>The product of a constant factor of seven and a factor with the sum of two terms.</em>
