If I have something like -x^2 when I plug the number in, will it be positive or negative and why
MrRissso [65]
The order of operations tells you exponentiation is done before multiplication or addition. That is, the value of x is squared before the sign is applied.

Your result will be negative for any non-zero value of x.

Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negati
sdas [7]

Answer:

the following 3 equations are equivalent :

• x + 1 = 4

• 2 + x = 5

• -5 + x = -2

Step-by-step explanation:

2 + x = 5

x + 1 = 4

9 + x = 6

x + (- 4) = 7

-5 + x = - 2

Let’s take this equation :

x + 1 = 4

=======

By Adding 1 to both sides of the equation we get :

x + 1 + 1 = 4 + 1

⇔ x + 2 = 5

⇔ 2 + x = 5

Then the equations x + 1 = 4  and 2 + x = 5 are equivalent.

…………………………………………………………………

On the other hand ,if we subtract 6 from both sides

of the equation x + 1 = 4  we get :

x + 1 - 6 = 4 - 6

⇔ x - 5 = -2

⇔ -5 + x = -2

Then the equations x + 1 = 4  and -5 + x = -2 are equivalent.

15 1/4 acres of land are to be divided into lots of at least 2/3 acres each What is the maximum number of lots that can be creat
Sholpan [36]
Well, if you want the maximum number of splits, then you want to make
each individual split as small as possible. 
That's 2/3 acre.  How many will that give you ?

                  (15 and 1/4) divided by (2/3)

             =      (15.25)  /  (0.666...)  =  22.875 pieces .

The maximum number of 2/3-acre lots you can sell is 22 lots.

Then you have 58.3% of an acre of land left over that you can't sell
because it's less than 2/3 acre.  Sadly, that 58.3% of an acre is just
about the size of the lot that I've been living n for almost 30 years. 
You really know how to rub it in, dontcha !
