1.) 9(4) + 8(5)

36 + 40 = 74

2.) 2(3) + 8(3)

6 + 24 = 30

3.) 4(5) + 7(5)

20 + 35 = 55

4.) 10(4) + 18(5)

40 + 90 = 130

5.) 2 + 8(1/4)

2 + 2 = 4

6.) 9(1/3) + 8(1/4)

3 + 2 = 5

7.) 3(8) + 7(4)

24 + 28 = 52

8.) 12(1/4) + 16(5)

4 + 80 = 84

X+y=5 x^y+y^x=17 solve for the value of y and x

pentagon [3]

X = 2
y = 3 

2 + 3 = 5 
2³ + 3² = 17 

------------------- 

BUT: 

x + y = 5 
x^y + y^ x = 17 

y = 5 - x

This is a geometric mean problem...a ratio. The geometric mean is the height of the triangle, 6. To solve:

$\frac{x}{6} =\frac{6}{3}$ and cross multiply to solve for x:

3x = 36 so
