It would be: √225 x⁸ = 15 x⁴
Answer:
D. 20
Step-by-step explanation:
20% of 20 is 4
Answer:
28
Step-by-step explanation:
-4×-4=16
3×4=12
12+16=28
Let's review the options:
A. 169-26y+y^2 can be factorised into (13-y)(13-y)
B. 81+18y+y^2 can be factorised into (9+y)(9+y)
C. 64+8y+y^2 cannot be factorised into double brackets
D. 25+10y+y^2 can be factorised into (5+y)(5+y)
Therefore your answer is the odd one out, C.
Answer:
1008
Step-by-step explanation:
geometric sequence:
a=16
r=32/16=2
Sum of GS:
s=a(1-r^n)/(1-r)
S(6)=16(1-2^6)/(1-2)
=1008
