Answer:
c). 14 < x < 15
d). 7 < x < 8
Step-by-step explanation:
c). (x/3)^3 = 124
Take the cube root of both sides
x/3 = 4.986630952238646
multiply both sides by 3
x = 14.959892856715938
14 < x < 15
-----------------------------
d). (x/2 - 1)^3 = 25
Take the cube root of both sides
x/2 - 1 = 2.924017738212866
Add 1 to both sides
x/2 = 3.924017738212866
multiply both sides by 2
x = 7.848035476425732
7 < x < 8
Answer:
they're equal
Step-by-step explanation:
Answer:
-1 • (x + 9)
Step-by-step explanation:
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle
