Answer:
15inch
Step-by-step explanation:
X^2=8^2+7^2
Answer:
slope= 11
Step-by-step explanation:
(12,23) = (x1,y1)
(14,45) = (x2,y2)
Now,
slope(m)= (y2-y1)/(x2-x1)
=(45-23)/(14-12)
=22/2
=11
Answer: 1 9/16
Step-by-step explanation:
-2|-2r-4|=-12
divide by -2
|-2r-4| = 6
we get a positive and negative solution
-2r-4 = 6 and -2r - 4 = -6
-add 4 to each side
-2r = 10 -2r = -2
divide by -2
r = -5 and r = 1
Answer r = -5 ,1
