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:
Your answer is 17.5
Step-by-step explanation:
Turn your fraction into a decimal
2/5 = 0.4
Next multiply my given answer by 0.4
17.5 x 0.4 = 7
Therefore 17.5 is your final answer
X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2
Hope this helped!
