Well, for the first question, the answers will be (a) 13 per row, because 13*13=169, and (b) a square, because the dimensions will be 13x13.
Answer:
4(x+1)/(4x+5)
4(x+1)/(5-4x)
4(x-(-1))/(4x+5)
Step-by-step explanation:
The numerators in the fractions must equal to 0, or else the expressions won’t have the result of 0.
4(x+1)
4(-1+1)
4(0)
= 0
4(x-(-1))
4(-1-(-1))
4(-1+1)
4(0)
= 0
The expressions with the numerator as 0 have the result of 0.
