Answer:
20
Step-by-step explanation:
Simplify both sides of the equation.
−4=
r
20
−5
−4=
1
/20
r+−5
−4=
1
/20
r−5
Flip the equation.
1
/20
r−5=−4
Add 5 to both sides.
1
/20
r−5+5=−4+5
1
/20
r=1
Multiply both sides by 20.
20*(
1
/20
r)=(20)*(1)
r=20
The formula would be something like, P×h+(B × 2). Hope this helps.
