(8) =b
explaintion is : 3 seven times is 21
Here you go:
1) 0.3 = 3/10
2) 0.125 = 1/8
3) 0.16 = 16/100 = 8/50 = 4/25
4) 0.1 = 1/10
5) 0.6 = 6/10 = 3/5
6) 0.2 = 2/10 = 1/5
7) 0.75 = 75/100 = 3/4

49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
