well, the pencils are 9 bucks, but they're selling for 9.63, meaning the tax is 0.63 or 63 cents.
now, if we take 9 to be the 100%, what is 0.63 off of it in percentage?
Answer:
There's no real solution to your question but thats what I got

Diagonal of the left triangle = ((8)^2+(7)^2)^0.5= (113)^0.5
x =( 12^2 -(113)^0.5)^2))^0.5=( 144- 113)^0.5= (31)^0.5= 5.57
For ur working, ur mistake lies in the line : x^2+12^2=10.6^2
It shld be 12^2= x^2+10.6^2
Answer:
−(d+1)>3
Step 1: Simplify both sides of the inequality.
−d−1>3
Step 2: Add 1 to both sides.
−d−1+1>3+1
−d>4
Step 3: Divide both sides by -1.

d < -4
