If x2 = 20, what is the value of x?

Step-by-step explanation:

Given:

The given equation to solve is:

In order to solve the above equation, we take square root on both the sides.

While taking square root on both sides, we must consider both positive and negative values. So, this gives:

From the definition of square root function, we have

Therefore,

Now, writing 20 into the product of its prime factors, we have

Therefore,

We also know,

So,

Therefore,

So, there are two values of 'x'. They are:

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
