Answer:
5.) MIGHT I SAID MIGHT be 20+16+12=48km squared for perimeter and 192 (im not sure really) for area
i can only do one I HOPE this helps probably not tho
Step-by-step explanation:
Hello!
For this you can plug in the x values in the choices and see if you get the y value
y =

-4^3 is -64
when you subtract a negative you are just adding
-64 + 4 = 60
Then you do the second one

-3^3 is -27
-27 + 3 is -24
Then the third one

-2^3 is -8
-8 + 2 is -6
Then the last one

-1^3 is -1
-1 + 1 = 0
Since we did not get -2 the answer is D
Hope this Helps!
Answer:
Associative Property
Step-by-step explanation:Because it includes grouping of three numbers and the parentheses group around two different numbers
9514 1404 393
Answer:
14 units
Step-by-step explanation:
The angle bisector divides the sides proportionally, so you have ...
(x+4)/8 = (2x+1)/12
3(x +4) = 2(2x +1) . . . . . . multiply by 24
3x +12 = 4x +2 . . . . . . . . eliminate parentheses
10 = x . . . . . . . . . . . subtract (3x+2)
Then BD = x+4 = 10 +4.
The length of BD is 14 units.

<em>Additional comment</em>
The "triangle" cannot exist, as the side lengths are shown as 8, 12, and 35. The long side is too long. Nice math; bad geometry.
