Answer:
Step-by-step explanation:
6
Let's solve for x.
Layout equation:
a/b
(2x−12)=c/d
Step 1: Multiply both sides by b.
2ax−12a=bc/d
Step 2: Multiply both sides by d.
2adx−12ad=bc
Step 3: Add 12ad to both sides.
2adx−12ad+12ad=bc+12ad
2adx=12ad+bc
Step 4: Divide both sides by 2ad.
2adx/2ad=12ad+bc/2ad
So the answer is x=12ad+bc/2ad.
We know that
in the right triangle ACD
Applying the Pythagoras theorem
AC²=AD²+CD²------> AD²=AC²-CD²-----> AD²=5²-4²---> AD²=9----> AD=3
let
∅=angle CAD
tan ∅=4/3
in the right triangle CDB
the angle DCB is equal to ∅
tan ∅=DB/CD-------> DB=CD*tan ∅------> DB=4*(4/3)----> DB=16/3
AB=AD+DB-----> 3+16/3----> AB=25/3----> AB=8.33
the answer is

Answer:
Jack is evil.
Step-by-step explanation:
Jack wasn't very smart, one-day jack made a science experiment to increase the temperature of frogs 2 fold every week starting from 2 degrees Celcius, the graph shows how much he cooked the poor frog in the weeks that sadly, followed.
(in case you don't know fold just means multiplied by that much so 20k$ going 10 fold is 200k$)
