how much is one acre i cant find out and i want an exact answer because all the things online say between this number and that number and it bothers me so please tell me what the answer is so i can go back to my school and feel confedent bye bye and yes i am a tomboy

Type this in the google search engine:

1 acre in square feet

One acre is exacly 1/640 of a square mile. "Forty acres", a unit in which some homesteaded plots were divided, is exactly 1/16 of a square mile, which could be a square 1/4 mile on a side, for example.

If you want a conversion of acres to square feet, hectares or square meters, may I suggest

How do I do I simplify a problem like this 3x+2/15x(sqaured)+16x+4

To simplify the expression 3x + 2 / 15x^2 + 16x + 4, you need to follow the order of operations and combine like terms.

First, let's handle the numerator, 3x + 2. Since there are no like terms, it cannot be simplified any further.

Next, let's focus on the denominator, 15x^2 + 16x + 4. This can be simplified by factoring.

The given expression becomes:
(3x + 2) / (15x^2 + 16x + 4)

Now, let's factor the denominator:
15x^2 + 16x + 4

To factor quadratic expressions like this, we need to find two numbers that multiply to give the product of the coefficient of the x^2 term and the constant term, which is 15 * 4 = 60, and also add up to the coefficient of the x term, which is 16.

The numbers that satisfy these conditions are 10 and 6.

So, we can rewrite the expression as:
(3x + 2) / [(5x + 2)(3x + 2)]

Notice that the factor (3x + 2) appears in both the numerator and the denominator. We can cancel them out, which simplifies the expression further:

(3x + 2) / [(5x + 2)(3x + 2)] = 1 / (5x + 2)

Therefore, the simplified form of the expression is: 1 / (5x + 2).
