Answer:

x=11

Step-by-step explanation:

because a each angle of a square or rectangle is 90° which means you add 9 to 90 and then divided 99 by 9 which is 11

Answer:

x = 11

Step-by-step explanation:

9x - 9 = 90

    + 9  + 9

9x = 99

9x/9  99/9

x = 11

Answer:

d = \sqrt{65}

Step-by-step explanation:

We need to find the distance between the points (5, 2) and (1, 9). In order to do this, we will use something called the distance formula. The distance formula is written as follows:

d = \sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}

Now we need to plug in our points which we have given in the form (x, y):

d = \sqrt{(5-1)^{2}+(2-9)^{2}}

Next, perform the operation of subtraction inside the parentheses to simplify:

d = \sqrt{(4)^{2}+(-7)^{2}}

The exponent is the next step in the order of operations, so square 4 and -7:

d = \sqrt{16+49}

Finally, add 16 to 49:

d = \sqrt{65}

The square root of 65 cannot be simplified further, but an approximation can be made.

\sqrt{65}  ≈ 8.062257748

Simplify 10 to the 6 power over 10 to the negative 3
dimulka [17.4K]
To simplify 10^6/10^-3 you first need to get rid of the negative exponents so you bring up 10^-3 so it becomes:
10^6x10^3 then all that you have to do is add the exponents since the bases for both are the same.
So the final answer is:
10^9
Or in other words:
10 to the power of 9
