Anyone know how to find the missing length ?

so i'm assuming you'd use Pythagoras:

so 15^2-12^2=81

square root it=9 which is I

to find T we do 41^2-9^2=1600

square root that is 40 so T=40

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet

hope i
