Screen-printing a batch of shirts requires 1 minute per shirt in addition to 2 minutes of initial set-up time. If it takes 42 minutes to screen-print a batch of shirts, how many shirts
are in the batch?

40 shirts

Step-by-step explanation:

First you subtract the initial time to figure out how much time it takes printing:

42-2=40

It takes 40 minutes printing. It's 1 minute per shirt, during 40 minutes, so 40×1=40 shirts

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
