I think the answer is 62 cm2
I can't see the whole problem
its the first one
Step-by-step explanation:
because per pertains to to x
X would have to equal 2 because when you multiply that by 7 you get 14 then add 3 and you get 17
64 = 2 ^6
16 = 2^4 =
2^ 6*(2x+4) = 2^4 * 5x
6(2x+4) = 20x
10/3 x = 2x +4
4/3 x = 4
x = 3
you can also use logarithms like so
(2x+4)ln64 = 5x ln16
ln64/ln16 = 3/2
3/2 * 2x + 3/2 * 4 = 5x
3x + 6 = 5x
2x = 6
x = 3
