Answer:
Step-by-step explanation:
6)a)

7a) y² - 5y - 14 = y² -7y +2y - 2*7
= y*(y - 7) + 2*(y - 7)
=(y - 7)(y + 2)
b) Use FOIL method

c) Rationalize the denominator by multiplying the denominator and numerator by √12

Your molarity would be 0.975 M HCl because it’s moles of solute divided by liters of solvent
9)

10) The y-intercept is always the constant term (without

). Therefore, the y-int is -9. The slope is always the term in front of the

, and so it is 3.
Perimeter = 2(length + width)
16.8 = 2(3.6 + width)
3.6 + width = 16.8/2 = 8.4
width = 8.4 - 3.6 = 4.8 in
