Answer:
B
Step-by-step explanation:
3 power of 4 equal to 81
3 power of 2 equal to 9
81/9 = 9
Step-by-step explanation:
the lengths OB, OC & BC together forms a isosceles triangle.
therefore,
OB=OC
3x+4=x+8
2x=4
x=2.
OB = 3x+4= 3.2+4=10cm.
OC= x+8= 2+8=10cm.
therefore, the diagonals are : 20cm each.
hope this helps you.
8+5+8=21 coins in total.
8/21*7/20=
56/420=
2/15. Hope this helps, and PM me if something's not clear!
Answer:
-8x^3+4xy
Step-by-step explanation:
-4x·2x^2
Multiply the like terms
-8x^3
Two negatives equal a positive so
-4x(-y)
=+4xy
Therefor the answer is:
