d(4) = 64

Step-by-step explanation:

Using the recursive formula

d(n) = d(n - 1) + 17 with d(1) = 13, then

d(2) = d(1) + 17 = 13 + 17 = 30

d(3) = d(2) + 17 = 30 + 17 = 47

d(4) = d(3) + 17 = 47 + 17 = 64

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
