Yes, the decimal form of 
is indeed a repeating decimal. The expression is equivalent to 
, which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.
1)
45x^3+5x
the GCF is 5x because that is a factor of both.
The answer would be 5x(9x^2+1)
2)
u^2-5u+6
factoring is finding what multiplies to the last number to add to the middle number. Those numbers are -3 and -2.
the answer would be (u-3)(u+2)
3)
m^2-49
difference of perfect squares
answer is (m+7)(m-7)
4)
x^5+4x^4+3x^3
GCF is x^3 so it's x^3(x^2+4x+3)
Factor that and it's x^3(x+3)(x+1)
Answer: b = 20 c = 160
Step-by-step explanation:
the value of a straight angle is 180, so 180-20= 160
