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:
-4u+4
Step-by-step explanation:
105,159 rounded to the nearest ten thousand is 100,000
Answer:
Step-by-step explanation:
2 * 2 = 4u² (area of the central square)
2 * 2 : 2 = 2u² (area of one congruent triangle)
4 + 2 + 2 = 8u²
(u = units)
