Answer:

8. P=10X+16Y+14

9. a^2+8a-10

10. 15v+22w

11. 10c^2+4c

12. z^3-8z^2+5z+23

Step-by-step explanation:

8. P=2(l+w)

P=2((2x+7)+(3x+8y))

P=2(5x+8y+7)

P=10x+16y+14

9. 3a+a^2+5a-10 = a^2+8a-10

10. 8v+8w+7v+14w  =  15v+22w

11.  4c^2+6c+6c^2-2c  =  10c^2+4c

12. z^3+5z+15+8-8z^2  =  z^3-8z^2+5z+23

Answer:

  $557.51

Step-by-step explanation:

A financial calculator tells you the payments are ...

  on $80,000 at 4.75%: $417.32

  on $20,000 at 7.525%: $140.19

Then the total monthly payment is ...

  $417.32 +140.19 = $557.51

_____

You can use the amortization formula to find the payment (A) on principal P at interest rate r for t years to be ...

  A = P(r/12)/(1 -(1+r/12)^(-12t))

I find it takes fewer keystrokes to enter the numbers into a financial calculator. Both give the same result.

2. Dilute hydrochloric acid reacts with zinc to form zinc chloride and hydrogen.
DIA [1.3K]

Step-by-step explanation:

Zn + 2HCl => ZnCl2 + H2

Moles of Zn = 13g / (65.38g/mol) = 0.198mol

Volume of HCl = 0.396mol / (0.25mol/dm³) = 1.58dm³.

Volume of H2 = 0.198mol * (22.4dm³/mol) = 4.43dm³.
