I’m pretty sure there not but I might be wrong
Answer:
C, 4.123
Step-by-step explanation:
√(17) which equals 4.12
Alright, so what we can take as a given is that arcDE/2= ∠CDE=2x+20 since the arc corresponding to the angle is 2*the angle. To solve for arcDE, we multiply both sides by 2 to get 2(2x+20)=4x+40=arcDE. Since the arcs in a circle add up to 360 degrees and we only have -20+30x and arcDE, we have -20+40+4x+30x=360 using the associative property. Simplifying, we get 20+34x=340. Subtracting 20 from both sides, we get 340=34x. Next, we can divide both sides by 34 to get 10=x.
Answer:
B
Step-by-step explanation:
When you double the dimensions of a triangle, the area is four times as large, so if you quadruple it, it would be 16 times as large
Answer:
x > 9/2
Step-by-step explanation:
don't get scared :) we can isolate the variable easily!
distribute
5 -2( 3x-4) -2x < -6x + 4
5 -6x + 8 - 2x < -6x + 4
-8x + 13 < -6x + 4
+6x -13 +6x -13
-2x < -9
x > 9/2
change the direction of the sign because we divided by a negative
There you go!
I hope this helps (:
