Answer:

Distance between the school and the theater = 2\sqrt{13} units

Step-by-step explanation:

Use distance formula to calculate the distance from the school (8, 7) and the theater (2, 3):

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let,

school (8, 7) = (x_1, y_1)

theater (2, 3) = (x_2, y_2)

Plug in the values into the distance formula

d = \sqrt{(2 - 8)^2 + (3 - 7)^2}

d = \sqrt{(-6)^2 + (-4)^2}

d = \sqrt{36 + 16} = \sqrt{52}

Simplify

d = \sqrt{4 \times 13}

d = 2\sqrt{13}

2) Evaluate 9 X 364 – 9 X 125 – 9 X 39 without the use of your calculator
Brums [2.3K]

Answer:

<em>9*364 - 9*125 - 9*39 = 1,800</em>

Step-by-step explanation:

<em>Mental Calculation</em>

If we detect known patterns in the calculations, we could easily give their results without the use of calculators.

We are given the expression to evaluate:

9*364 - 9*125 - 9*39

The first thing to note is the 9 is a common factor of all terms, thus we take it out:

9*(364 - 125 - 39)

The negative numbers can be easily added

     125

+     39

------------

     164

Now our expression is much easier:

9*(364 - 164)

The subtraction of 364-164 is 200, thus the result of the operations is:

9*200. We only need to recall 9*2=18 and add two zeros to get 1,800, thus:

9*364 - 9*125 - 9*39 = 1,800
