Distance formula
D = √((x1 - x2)2 + (y1 - y2)2) We have three distances that we are dealing with. Between the Theater and the Park, between the Theater and the Pier, and between the Park and the pier. In both routes we have to go between the Theater and the Park. The distance between those is the same regardless of which way we go, so we can ignore doing the math for that. That leaves us two distances. Let's plug them in. Theater to PierD = √((0 - 10)2 + (3 - 9)2) = √(100 + 36) ≈ 11.6619 Park to PierD = √((2 - 10)2 + (1 - 9)2) = √(64 + 64) ≈ 11.3137 11.3 < 11.7

Answer: 288
Workings : 16 x 12 =192 (for bottom rectangle bit) 12x 16 =192 then divide 192 by 2 =96 add them together and its 288
<em>Answer:</em>
( B ) x = 6.5
<em>Step-by-step explanation:</em>
We know that all the angles of a triangle equal 180 when added together. So lets make an equation for this question.
(10x-10) + (10x+8) + 8x = 180
I just took all the angles and added them together to make 180. Now solve for x.
10x - 10 + 10x + 8 + 8x = 180 <em>(combined like terms)</em>
28x -2 = 180 <em>(added 2 to both sides)</em>
28x = 182 <em>(divided both sides by 28)</em>
x = 6.5
Considering the place value of the digit 9, in the first number, the decimal value of 9 is thousands. In the second number, the decimal value of 9 is hundredths. The conclusion we are drawing is: The second decimal is 10 times larger than the first one
