[1 - n ] / [3 - 2] = 6
[1 - n ] /1 =6
1 - n = 6 add n to both sides, subtract 6 from both sides
-5 = n
50000(1 +.0425)^3 = $56,649.77
20000( 1 + .0425)^3 = $ 22659.91 + $35000 = $ 57,659.91
The second is better by $ [57659.91 - 56649.77] = $1010.14
[ - 4 - c ] / [ - 6 - - 4 ] = 7
[ - 4 - c ] / [ -2] = 7 multiply both sides by -2
-4 - c = - 14 add c, 14 to both sides
10 = c
distance = sqrt [ (15 -3)^2 + (12 - 7)^2 ] = sqrt [ 12^2 + 5^2] = sqrt [ 144 + 25 ] = sqrt [169] = 13 units
5/6(1/2x+6)-3x = distribute the 5/6 over the terms in parentheses
(5/6)(1/2)x + (5/6)(6/1) - 3x
(5/12)x + 30/6 - 3x
(5/12)x + 5 - 3x 3x = (36/12)x
(5/12)x + 5 - (36/12)x combine like terms
(-31/12)x + 5
7x - (25x^2 + 12x) distribute the negative outside the parentheses over the terms inside
7x - 25x^2 -12x combine like terms
-5x - 25x^2
4x - 1 = 81 add 1 to both sides
4x = 82 divide by 4 on both sides
x = 82/4 = 41/2
"D" is correct

SecA = 1 / cos A
Tan (135°) = - 1
The perimeter = 2 [ L + W],....so.....
16 = 2 [ L + W] or
8 = L + W
So...the possible combinatons are
1 + 7
2 + 6
3 + 5
4 + 4
