Answer:
r = ±√47
Step-by-step explanation:
-7r^2 = -329 . . . . given
r^2 = 47 . . . . . divide both sides by -7 (multiplication property of equality)
r = ±√47 . . . . square root both sides (square root property of equality)
Answer:
Subjective Point of View
Step-by-step explanation:
It's subjective point of view because in the text it says "Goals are built into games to keep us coming back for more" that's not really a fact it's more likely a thought therefore the author mostly uses Subjective point of view, and some part of the text is also a mix with subjective and objective.
ABC is a equilateral triangle .
Proof :-
Let's assume both circles as C1 and C2 [ as shown in the figure ]
- AB is the radius of circle C1
- AB is the radius of Circle C2
AC is the radius of circle C1.
BC is the radius of circle C2 .
AB and AC both are radius of circle C1 so both are equal ie AB = AC .
AB and BC both are radius of circle C 2 so both are equal ie AB = BC .
Hence we conclude that .
AB = BC = AC.
So the triangle is equilateral triangle.
L*W=51
L=W+4
Replace L with W+4: (W+4)*W=51
W²+4W-51=0
use the quadratic formula to find W:5.4 (sorry cannot type the formula here)
the length is 5.4+4=9.4
