Remark
I'm going to interpret this equation as
D = ut + kt² The only difference is the 2.
Solution
Subtract kt² from both sides.
D - kt² = ut Now divide by u on both sides.

The t's cancel out. on the right. You are left with u on the right.

X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
Well the first problem that i solve is you have to move 12 it will give you
-3y power 12 - 3y + 12
Answer:
a number more than 1 is 2 or 3 or literally anything bigger
Divide 1.28 by 2 answer .64 notepads divide by 3. u get .29 each so add .29 twice. u get .58 add 1.59 twice. u get 3.18. pens 1.98. add .64 + .58 + 3.18 + 1.98= 6.38 so answer is A
