**Answer:**

1) 8y+20

2) 20x-8

**Step-by-step explanation:**

1) Perimeter= Sum of all sides=2*(2y+4)+3y+9+y+3=8y+20

2) Perimeter=Sum of all sides=4*(5x-2)=20x-8

**Answer:**

62

**Step-by-step explanation:**

divide 29 by 42 and multiply the answer by 100

**Answer:**

**Step-by-step explanation:**

The graph shown is f(x)=y=|x|

The required graph is g(x) = |x|-3 = f(x) -3

In general, the graph of f(x)-3 is 3 units below f(x), and has the same shape.

See attached graph. y=f(x)=|x| in blue, f(x)-3 = |x|-3 in red.

The answer would be (6,0)

Assuming continuously compounding interest:
A = Pe^(rt)
A = Pe(0.02)(3)
A = P(1.062)
P would be about $417:
A = (417)(1.062) = $442.85
$442.85 - $417 = $25.85
