Claire says that she can draw an obtuse equilateral triangle. Is she correct? Explain.
notka56 [123]
No, because an equilateral triangle is also equiangular so all sides must be 60° (60+60+60=180) and an obtuse angle is more than 90° so the triangle would not be equilateral.

Hope I Helped (:

Which expression shows another way to write 36+16?<br> 4(9)+4<br> 4(9+4)<br> 6(6+8)<br> (6+4)(6+4)
allsm [11]

Answer:

36+16= 52

4(9)+4= 40, which does not equal 52.

4(9+4) = 52.

6(6+8) = 84, which does not equal 52.

(6+4)(6+4) = 100, which does not equal 52.

So, 4(9+4) is correct.

Let me know if this helps!

Two bees have found a food source. The first bee’s path to the hive follows the line . The second bee’s path follows the line y
choli [55]
The coordinate of the hive is the point of interaction of the two lines. 
We have the two equations:
y=4/5x\\y=-2x+3\\\text{By substitution we get:}\\4/5x=-2x+3\\\text{Solving the above equation for x we get:} x=15/14\\\text{Then }y=4/5\times15/14=6/7\\\text{The coordinates of the hive are then :}(15/14,6/7)
